My Sims Can't Get Married after patch

Hi, my sims can't get married after that My Wedding Stories patch. How can I fix this? I got rid of the UI Mod and aside from CAS and BB items, that was the only the mod I had. 

I click on the arch and it the option to "exchange vows" or "get married to" are greyed out and it says "The engaged sim isn't here" when both sims are on the lot and near the arch.
