Pinnacle insert plate question...

What I’m using: Kreg router table top/Fence/Stand, Triton router, Pinnacle aluminum insert plate (drilled access for router lift).

I’ve spent the day putting everything together and I get to the point where I’m ready to put the router on the insert plate and get ready to level.

Using the provided levelers from Kreg, I lower the 4 inside levelers so they would have no effect and just use the 4 outside to do the leveling.

Working front to back I used a straight edge over the span of the insert opening to get the back flush with the table top, lightly pressing on the front, making it obviously lower. This worked out great!

Moving to the front of the insert I moved my straight edge and proceeded in the same fashion. Success again. I thought I was all done and ready to put the fence on.

After I removed the straight edge I noticed that the back right corner of the insert wasn’t flush anymore. I pressed on it and the the front right corner popped up.

Anyone else had this problem?
