Matomo conflict wpallimport

I’m not sure what happened and when but my admin is totally messed up when I go to importing or exporting. Also editing existing exports/imports gives pages which are totally messed up. I reinstalled all wpai plugins and no help. Tried cache off and no help. When disabling matomo plugin, everything started to work normally and wp all import/export pages started to work. Every other page in admin seems to be fine but all pages which are for wp all import or export are broken. WPai developer asked to contact to matomo developers. How to proceed? Here are some pictures:
