On my IPad 2 in insert effects I get down to the 19th app and then they disappear if I scroll any further. However, in send effects I get as far as the 21st app before it goes blank. I also have quite a few duplicated entries, but that may be a separate issue...
Exactly the same glitchy behaviour here on ipad air ^^
