RAB and [Wasta]Linux

I just want to share some issues/bugs I found in the Linux RAB-Version under [Wasta]Linux 20.04.1 (I try to update the computer a least every two weeks):

Fine tune Timing is not working correct. Firefox not allows you to save the changes in the Fine-tune-timing file, the save Button is missing.

Expiry
RAB does not allow you to choose a specific date.

So far for now.
