Hello,
thank you for the report.
I found the section causing this. But this should only occur once after a clean install.
can you please navigate to one of the categories in the drop down and confirm that the log is not showing up anymore?

thank you

Yes it does happen only once whenever the app gets activated so if I turn it off and on again I will see it in the log again.
