[1.6.1] Planned pending transaction changes when its logged one changes

I have some planned transactions set up as pending, cause they dont have a fixed price (like energy cost). I set them up as pending, so that on the day I pay them I can edit the amount and mark the transaction as no longer pending.

However, this action messes up with future planned transactions - because it changes them to what I just did for this month payment.

Like, if I have a "Energy" planned pending transaction set on every 10th of month, with amount of $100. Now, when it gets logged on January 10th as the pending transaction and I edit it to $123.23 and mark it no longer pending, the future planned transaction from 10th of February will ALSO change to $123.23 and will be no longer marked as pending.

This seems like a bug, because editing an existing logged transaction should rather not change the future planned transaction?
