We apologize, but we couldn't reproduce the issue. This could be linked to your Altium units default setup, which can be easily changed by clicking on the View tab, then on Toggle Units in the schematic view, or on Panels>Properties>Other on the footprint view.
You can follow this link for more information:
If you have any development on this issue, or if you have any other inquiries, please let us know - we'd be glad to help!

We were able to reproduce this error and it is happening to some of our symbols so we're currently finding them all and updating the symbol files.
In the meantime, I have updated the symbol for the 282837 series so you can download them now and the grid is set to mil now. I have requested our CAD team to update the symbol for the LTM4644EY_PBF, we will keep you posted!
