Picmi row and column numbers dont turn grey

Hey guys,

i run into an issue lately. I installed picmi (the 2nd one if you search for "picmi" in the Software Center. It has the TV icon).

Bug?: The numbers never turn grey.

I run Ubuntu 16.04.5 LTS on a Lenovo Laptop if that matters. I upgraded it from 14.04.5 LTS.

Uninstalling/removing, autoremoving and installing again didnt work.

For some reason picmi runs (fine/without this bug) on my other computer (also Ubuntu 16.04.5 LTS).

A possible explanation for this COULD be that i installed picmi on this laptop first and then upgraded the OS to 16.04.
However, resetting the whole system in order to MAYBE fix this bug, would be a real pain (create backups and stuff...).

I appreciate any tips/help :)
