Why do I have to keep typing in my master password?

I have a little bit different question related to the master password. I have three different accounts connected to my 1Password (two personal accounts and one account for teams). In 4 from 5 attempts when I enter the master password, the two personal accounts unlock automatically, but the account for teams keeps locked. Then I have to enter the password of the locked account to reach the stored items. This behaviour is new for 1Password 8 for Windows, the previous version and iOS mobile version works as expected, all connected accounts are unlocked by the master password automatically.
