WhonixRepository wont save what you have choosen:
- Open WhonixRepsitory GUI switch it from stable to tester or any other repo then open it again = you will see the option ticked on stable again. Though in whonix.list already switched to tester.
Switching from stable to tester repo using whonixrespository tool it will switch to whonix clearnet even if you were using whonix onion stable repo before that. it will always shifting you to clearnet repo.
suggestion: if the user on clearnet switch to whonix clearnet tester , if hes on onion switch to onion.
