Spelling correction in Notes section is buggy

When I misspell a word in the Notes section it will mark it with the red line underneath. What I naturally do is right click the word and sure enough it offers me a list of corrected spellings. Now the issue is that I click on the correct spelled word and would expect that the error is corrected. However that does not happen. The incorrect word just stays there. When I try it the second time it sometimes works. Usually the third time I try it it gets finally corrected. That is a very annoying bug.

Also once in a while it will underline correctly spelled words for a short time after I typed them. This usually goes away after a few seconds but is never the less annoying
