Replying to Setup help plz

Currently I have K2 poachers with the pivot 15 GW. Bought some new Roxa element 120 boots last year and 4th time I used them the tongue on the left boot came off clean when putting the boots on. Cant say im impressed with Roxa quality/fit considering the high price tag. The boots didnt actually clip in properly with the Grip walk soles - there wasnt enough clearance for the heel to clip in so i had to remove the gw soles and put on the normal pair they came with. Even though i went through the process of getting fitted by a professional who solely does bootfitting and has been doing so for over a decade, i feel like the boots don't fit well. Should i try and get a replacement tongue and keep skiing on them considering how little ive actually used them or should i go back to my old pair of boots that are just alright?
