Grid disappears / behaves strangely after importing parts

I’ve just noticed something ‘new’ on my iPad (Pro): When I import parts (mostly from GrabCad), the grid suddenly behaves strangely. When zooming in, the grid suddenly disappears. I have also noticed that the value in the grid size (top right in my case) does not go below 10mm anymore. If I delete the part, the grid behaves normally again and the grid size goes down to very small numbers.

I have already tried everything, restarting, saving the project, exporting in Shapr format - it stays the same.

The effect does not occur with every part - but with some of them and it is reproducible.

Could you please submit a ticket on the support portal?

I ran into the problem of the grid being off and would appreciate if you guys would explain this.

It is fortunately only related to a couple of sketches exported/imported from another Shapr-file into new project. These are the only ones now having the grid off center and as I’ve tried to move them bodies related disappears.

How can this be alleviated and more so understood? It would be nice for me w/ a better understanding of the purpose of Plane and Projection in History features if you can advice on that as well.
