Snap to grid issue

[KayLynn Kraybill]

I am using THERM version 7.8.74.0.

Within preferences despite having "snap to vertical", "snap to horizontal", and "snap to grid" turned off, it is still snapping to the grid. This happens whether the grid is visible or not, and no matter what size the grid is set at.

Please advise if you have any idea what I can do to get my polygons to snap not snap to the grid and start snapping to my underlay. Thank you!
