Hi Dik,
Some objects have a different axis system like Z is up instead of Y. Which sometimes means a model can come in like 90º rotated. Is that what you experience?
Any other amount of degrees, not dividable by 90º indicates that the model was not oriented in its own space.
Please have a look here:

There are so many formats and options that I believe that what I wrote above is the only general information I can give.
There is a Reset-PSR command available, is that not able to fix the problem?
Can you share a file, or name the object from the Content Browser? If you have problems uploading here, I’m happy to provide an upload link (IF you share a link, please only Google, Apple, Amazon or [preferred] Dropbox).
All the best
