Similar to an issue i previously reported where the purge button was greyed out if opened on a screen with no flights, if i do the opposite, meaning i open lbp on a page that DOES have flights displayed (synced in my case) and then switch to the pending page, the "delete synced" button does not delete the synced flights.
If I do the same thing (delete synced) while viewing the synced tab, it works just fine.
