Common problems

Find the right control when a workspace will not open, a map or table stays empty, or values look wrong.

Where to find it

Start from the panel that shows the problem, then open Channel management, Track, Calculations or Settings as needed

Steps

Check the range
Look at the range button, laps and Region in the context bar. A panel with a pin badge uses its own range; Follow global selection links it again.
Check the channel
Open the panel's channel picker and search the original or custom name. Saved calculations and corrected channels are listed there too.
Check that calculations are saved
A preview is not saved. Save the calculation in Calculations, then add its output to the panel.
Check where it is shown
Saved marks appear only where Show on is ticked. Instrument inputs and ranges are in Settings → HUD.
Check the track calibration
Sectors, corners and straights need a saved calibration. Without one, an AiM XRK recording can still show the logger's split times as sectors in a lap table. After a calibration change, Lattiro switches back to the entire recording if the earlier laps cannot be matched; choose the laps again.
Check the account
If Confirm your account to continue appears, offline access has ended: connect and choose Sign in again. Your workspace and unsaved edits stay in the window.
Restart the analysis service
If Analysis service stopped appears, click Restart analysis service. Your open workspace and unsaved edits are still in the window.

The workspace folder is refused
The folder must be writable and on a local APFS or NTFS disk. Raw data folders are often read-only: start a new, empty folder with Create / open workspace and import the data into it. exFAT/FAT32 drives, NAS and cloud-sync folders are not supported.
The map is empty
If Multiple GNSS traces detected appears, click one of the channel pairs listed below it. If GNSS trace unavailable appears, read the reason below it. Once a trace is drawn, you can switch pairs in Map settings → View → GPS source, then wait for the map to refresh.
A lap-table cell is empty
Hover the cell to read the reason, such as Entry crossing missing, Not calibrated or Unit mismatch. Check the gates in Track calibration, or select the channel again in the metric settings.
Values or units look wrong
Display unit in a lap table only changes how values are shown; to change the conversion, use Channel management → Correction. If the vendor's software shows correct values but Lattiro does not, keep the original file.
Lattiro Assistant · Beta (invite only)
If the assistant does not answer, check that your account is in the beta, that you are signed in and online, and that allowance remains. With Your own API, use Test connection in Settings → Model services.
Updates
If Software updates shows Update did not complete with a reason, the check or download failed; it does not mean you are up to date. Downloading needs an online sign-in.
