Hi - we have realised after a day our laminated floor installation, it is bouncy on the edges. See video below. this is the worst one. It is like this in all edges.

What could be the reason and how could it be fixed?(if needed). We want to have some idea before we talk to the contractor.
Condition of the subfloor seems fine to me but attaching that one as well. Radiator was removed before installation.
