Zwiftpower/TOW listing ride as UPG

I done stage 4/ short ride of Tow today and zwiftpower listed it as upg. Aren’t these rides listed as group rides so power catagory don’t apply or am I wrong in this belief. Also my power numbers were no higher than some of my previous Tow rides. Anyone else had this issue or know why this is?
