Quests fail to initialize Fishing, Saint & Seducers on XBOX

[AsteroidLion]

XBOX Series X, fresh reinstall of game (install from disc, allow update, download creations and reinstall from load order) and creations from Bethesda  plus multiple Arthmoor mods 
With USSEP running, none of the quests in fishing, saints, contest will initialize, i.e., read the note and nothing happens.   At one point everything worked, then stopped; think that was after a recent  USSEP update.
IF I remove USSEP (and dependent mods) and run with Alternate Perspective, everything works fine. 
Need help as I really would like to continue with USSEP and dependent mods.
