Tools are snapping but aren't snapping

This has been driving me nuts. I am still new to this platform so I’m hoping its just a newbie issue. This example I’m using a center rectangle but it happens for most drawing tools. I hover my house over the center dot. It lights up purple indicating it has snapped. I click and start to dimension my rectangle only to find that it didn’t actually snap. Sometimes I catch it right away and other times I don’t, which is super frustrating. I’m not sure why in my photo you cant see the cursor but it is hovering over the center dot in the first picture.

We had a similar bug that was fixed in 5.630. Which version are you running on?
