Auto Spellcheck isn´t always working

Auto spellcheck has worked on all the languages I have used it in, but it doesn’t always work. I know I have some errors, but it doesn’t show even when I try to press the auto spellcheck button several times while sometimes marking the whole text and sometimes not and it is really frustrating and i don’t know what to do because I really need it to work

Thanks in advance.
