"Failover Priority" widget does not show the correct priority list (RUT9_R_00.07.06.16)

This sounds very similar to an issue I raised …

As in your case, despte the UI saying one thing, the actuat functionality was unaffected as the device used the metric configured in the config files.

Teltonika Dev stated that, in my case, it was a known issue that would be addressed in a further release.

If your metric is set correctly and you have expected functionality, then I guess Teltonika Support will have to comment.
