Why does Spellcheck turn off when I swap languages?

Spellcheck turns off when i swap languages

Hi everyone!

My spellcheck feature has been behaving rather odd lately. Perhaps someone could help me shed some light on the matter?

Problem:
The best way I can seem to explain this is that when I swap languages by using the world map button, the spell check function 'turns off'. I swap between French and English regularly (like, everyday) so it becomes quite frustrating over time

Examples:
-I want to type a message in English. Language is already set to English. No problem. Everything works fine.
-I want to type in French. Language is set to English. I don't realise until I start typing something. I hit the world map to swap to French. Spell check doesn't work anymore. It doesn't suggest words in French or correct mistakes. If I hit world map again to revert to English it still doesn't work.

Does anyone have the same problem?

This Problem 'appeared' out of the blue a few weeks ago. I didn't change any settings relates to typing and languages.

I hope it makes sense, if anyone knows what could be causing it is love to hear from you!
