When selecting some Quick Access proposal, it gets added to the Previous Pick list. However, some of those proposals might be volatile, not-retrievable from the related provider and get added anyway.
This makes a previous pick slot useless, and can -for cases where the processor isn't implemented at best- cause some issues.
Before storing the previous picks, the Quick Access should check whether the proposal is retrievable (by trying to re-build it from the previous pick info) and if not, just skip it instead of storing it.
