Printing with 1930s vintage diffusion enlarger

I was wondering if someone might be able to help me with a problem. I am
printing my collodion glass negatives with a 5x7 1930s vintage diffusion
enlarger. If I had an 8x10 camera I would be doing contact prints but I can
only go up to halfplate with my current camera.

The problem I am having is it has a hot spot in the middle. The hotspot
wouldnt bother me if it was only brighter BUT it seems to be making the
center more contrasty too when using multigrade paper.

I will be trying some graded paper soon but would like the option of using
multigrade too. Has anyone had a similar problem with one of these?

Best Regards,
