Multiple Budget Synchronized Bank Account Issue

I noticed something strange happen when I had two budgets using the same bank accounts. I first created a budget that use only manual accounts. Then I created another budget and connected synchronized accounts from my bank. That worked as expected. Then I wen back into the first budget and added some accounts from the same bank. They were added as expected, what I did not expect was for them to be removed from the second budget. It seems like the budgets are not 100% seperate and that somehow the synchronized bank accounts were conflicted between them.
