What is this problem called and how do I solve it?

To me it looks like the bed is low at the rear, this is just my opinion and I am not an expert.

First, perhaps try increasing the 'Z' offset in the slicer settings by small increments, eg.0.02mm at a time.

When I had a similar problem of a badly bowed bed on a Qidi X-CF-Pro, I ended up using strips of adhesive backed aluminium tape stuck to the actual heated bed until a replacement bed arrived.
Even had to use a small amount on the replacement bed.

Somtimes needed a few thicknesses.
