thank you very much for your prompt answer.
I was mainly playing around and as I'm impressed with SCIPs presolver I
wanted to try it out. But you are correct, SCIP is maybe not required

Interestingly enough, SoPlex says some of the problems (I have several
similar) are unbounded and some are not. GLPK solves them without any
problems and both solvers get the same results when SoPlex manage to solve
it. However, this is then really a SoPlex issue, so I'll move on in that
