Mastery List Bug

[CLIENT] Mastery List order randomizes after saving I sort my masteries into a numbered list that match a numbered rune page, and usually drag and resort the list regularly. Yesterday after changing a mastery page and saving, the list completely reshuffled into a random order. I finally got it to save correctly, but upon getting into champ select, it was again in a randomized order. I have repeated this many times, changed the titles of pages and even tried changing it back to how it was before this occured, and am still unable to save my mastery list in the order I want without it randomizing. I've noticed some varients, like certain pages will stay in the order I put them (ie Ashe1, ashe2, ashe2), but will have different pages surrounding them.

I included a video showing the list randomizing in champ select. Thank you
