Saved Queries Disappear

I have over 100 saved queries. Recently, only half of them show up when I log into Athena. Randomly, all of my queries will show up again but later disappear. I cannot find the missing queries even if I search by the query name. The behavior doesn't seem to have a pattern nor does it seem to be a lag in the UI loading. I've tried logging out and back in and that did not solve the problem.
