Plated Mounting Hole covered by SolderMask

I have used 3 plated Mounting Holes in my PCB which are connected to Ground.

In 3d Canvas: Out of these 3 holes, one hole is getting covered by SolderMask on Top and Bottom Layer while the others are shown OK.

Same footprint is used on all 3 holes and i ran Check>Design Status> Update Shape to Smooth to see if it helps but it doesn't.

Same result when i export this Step File Out of 3D Canvas.

Using latest hotfix 17.4 S023

Not prepared to put an email on a public site so you can upload your board onto the forum. If you don't want to put it here make a simple example (just the board profile and mounting holes) and upload that.

A Gerber file won't show the the padstack etc. Make a new board file, copy the profile and fixing holes ONLY into this board file (view it in 3d and make sure you see the same issue) then save it and upload that so we can look at the board file.
