Baro issue on stopping in Loiter

When i fly in Loiter forward than stop (release pitch stick), barometer height jumps up to 3 meters and drone strarts to descend:

Cube Orange+ inside enclosure, tried also external barometer in another enclosure covered in foam, but exactly same issue…
Any ideas?

Use more and better foam.

used a lot of foam, even put large box and put external baro in it with a lot of foam…

you can try this kind of something also. it really works very well.
