Why does my gender agreement keep failing when I switch between Persian-Arabic verbs and native Urdu ones?

I’m an intermediate learner and I feel like I'm hitting a wall. Even when I know the specific Persian-Arabic loanwords used in formal Urdu, I constantly mix up the masculine and feminine endings when attaching them to auxiliary verbs. Does anyone have a mental shortcut for identifying the gender of these borrowed abstract nouns, or do I just need to memorize them as part of my daily vocabulary lists?
