[Fused Riven mods disappearing from mod segment]

I have had this same issue but no one is even acknowledging its existence 

[Missing riven mod]

Same thing happened to me man

 

[Riven mod not appearing]

I was going through my riven mods as i was planning re rolling my twin grakata riven but, it was not in the modding station. Not in the riven mod section, all, and i even searched for it but couldnt find it. i went to my twin grakata and noticed the riven mod was still available to equip. but when i equipped it on its own and checked the modding of the weapon, it just didnt show up. this is a problem as i cant reroll it or upgrade it (if it wasnt already maxed). it wasnt like this before as i had already rerolled it once, i also have one riven mod slot available so space shouldnt be a problem.

Update: It's has been almost a full day and nothing i do will fix it. It is still taking up a mod capacity slot so i know it still exists
