Question about AOC 16G3 - Portable Display

Does anyone else have the following problem? In horizontal mode, the bottom right corner is about 5mm in the air. So every time I touch it, the monitor wobbles and rocks back and forth between the support and the corner. Quite annoying and if this is an isolated case, I will ask for a replacement. If they are all like this, I might as well keep it. The picture and other functions are great.
