Why do I have to add a PPA twice (once to add it to the list of repo, second time to fix a BAD GPG)

PPA

I notice the following:

I add a ppa using add-apt-repository, for example the wine ppa, mozilla security, nvidia drivers, etc..
When I go to the Update Manager and tell it to CHECK for updates it throws me a PPA error.
To solve the error I add the same PPA again.

Why do I have to add the PPA again (This also can be done by adding the received key alone with apt-key) but why does this problem happen anyway.
