Overlap Issues with QFN Package

Hello,

 

I am working on a 3.3V regulator using the TPSM861253. I downloaded the schematic and footprint from Ultra Librarian and SnapEDA, both of which show this problem. The footprint of the QFN package inherently has overlapping holes, pads, et cetera, which cause the part to fail the rule check. What is a possible workaround to this issue?

 

Attached is the .lbr file from SnapEDA and two screenshots: one showing the part in my PCB and one by itself. Both show the errors inherent to the footprint.

You WILL get errors like that when you have overlapping vias.
The errors are to warn you, in case you do it by mistake.
As the vias are placed there intentionally, probably for thermal relief, simply approve the error and it'll be gone.
