How to clear highlights

[knwin]

Dear Blazek,
Thaks for the LRS plugin. It is very useful.
There is one issue I am facing. I am using QGIS 3.44. When I high light calibration errors or locate measure with highlights, these highlights never disappear, no matter refresh or turn off the LRS layers.

I do not find how to clear the highlights in the help either. Is it my QGIS or something else causing this issue?

Best,
K
