Tips ignores my request to never be shown again

I use iTerm2 2.9.20160313 on OSX 10.11.3.

When the tips appears I set it to disabled and then close it. However on occasion the tips makes their appearance again. Its not after opening and closing iTerm but it does seem to happen if I have not had iTerm open for a day or two. It would be really nice that when I set it to now show me tips that it does so.
