Can’t See What I’d Typed

I was going to clear my inventory but I can see what I'm typing. This happens ever time I click the / to see the commands like clear the weather and stuff like that. This is not working on IOS nor java. This is getting really annoying I type a command wrong I have to do it all over again
I'm not a good speller either. It covers all of the commands hints. This happened in all game modes.
