Mat not aligned

On my 10 and 15 cubes the glass seems slightly bigger all around so there is some parts of the glass that are not supported. Is this a big problem?

Same on my 15 and 40.2. On my 40.2 the mat got compressed in the rear corners during shipping and it's not touching the stand in those areas. I asked WB about it and they said it's not a problem. You can contact them and ask the question, for assurance.
