Driver's Floor Mat Fastener

Mazda 6 Signature
Has anyone else had a problem with the driver's floor mat fastener on a 2018 Mazda6 (Signature)? Mine frequently comes out and it seems the "post" (lower) part doesn't fully engage with the "hole" (upper) part.

I'm considering replacing them with a different set of similar fasteners and would appreciate any feedback.

I have the all weather mats on my 2018 Mazda6 and I have the same problem. I was thinking about returning it for replacement ... assuming the dealership would do it.
Yes, I had this same problem on my 2018 Mazda 6 Signature.

I resolved it by removing the floor mat, prying apart the "hole" connector and then inserting some very small shims behind a few of the "prongs" that secure around the post. That was several months ago and the floor mat hasn't come loose yet.
