planned transactions / bookings - bug

Recently, planned transactions no longer disappear from the "planned transactions" list if I book them manually "today". As soon as I book the amount in the account overview (green tick), the amount appears in the account overview as "booked" (correct!), but also appears again (incorrect!) under "planned transactions". I cannot delete the individual entry in "planned transactions", only end the series transaction - but that cannot be the solution because I then have to create the series transaction again. The topic is a bit urgent because I have created around 40 series transactions on our joint account.

I have a 30 second video and tried to attach it here. Hope, that works, otherwise this explaination will have to be enough ;)
