losing softkey programming

I have the t46g and t21 phones, i provision from 3cx, then program the line buttons to be speed dials. then i lose programming on the keys i programmed. l have 2 exp40 modules on a t46 and the first one lost all its programming as well as all but the first two speed dial buttons i programmed. i searched the forums and couldn't find any help on this

also i have 44 rooms to program with speed dials on the phones. 3cx cannot program the softkey buttons, is there anyway to automatically do this so i don't have to manually imput the information? thanks
