Auto flight planner - bug or not?

About 1,5 years ago, I decided for myself, that flight planner is not sufficient, to fulfil my needs.

Several Versions later, there, in fact, has obviously been no improvement - but devs took away tools for planning manually, as discussed here.

For understanding, here my latest experiences:

Wednesday: Setup for auto-planner: first 2 flights per stand planned
less than 50% of all first auto-planned flights, planned correctly.
2 flights are planned with same timeslot

Thursday:
no more flights at the same time, luckily, but planned schedule is only hardly visible

Friday:
It is obvious, that flight planner won’t plan according to initial, wanted schedule, that’s why deactivated.
