Riven’s not showing up

[(XBOX)TheLostTitan761]

I’m trying to re-roll my Vitrica riven but when I go to my mods it says I have 7/15 rivens and only 4 show and I can’t find my Vitrica riven even if I search “Vitrica” it still won’t show up. I’ve checked my filters and everything but it won’t show up. If I go to my Vitrica and go to mods it would normally pop up right? No it doesn’t it’s like it doesn’t exist. I want to re-roll but I need to actually be able to see it to do so, please fix this or can someone tell me how to fix it if it’s on side. Thank you.
