I am in spectator mode and I have ignored myself but it still counts me. I have done the command multiple times and have reset the plugin too. Please fix this.

I turns out it only works if im in spectator.

From a quick test /ignoresleep works for me in spectator and survival mode. Are you in the same world as where the sleeping is taking place? The sleep counts are per world so e.g. nether & end won't count.

Can you test if you can get the issue without other plugins installed, or check if there are any errors in the console?

Since it's been two weeks without any updates I'll close the issue. If you do still have the issue leave a comment and I'll reopen it.
