Date , time, location etc are all correct.
Mount slews to target because it is well above horizon.

However if I want to have the same framing as a past session (of a day or few days ago) it says after plate-solving has succeeded, that the target is below horizon.

I've had this now twice with different targets in the past week or so.

Because of this I am not able to continue with past sessions.

I had this problem not in the past with the same equipment.

Is it a bug?
