Additional information:

It looks like this is the same issue as #4261 - although as matter overdrive has moved there issue reporting outside of github I'm not sure if it's going to be fixed anytime soon :(

Erm, although apparently a workaround is to set advancedItemTooltips to false in options.txt then it might work? (#4261 (comment))

Turned off the advancedItemTooltips and it worked, Weird, but now I know so if it happens to my friends I can also help them.
Thanks alot for the instant reply! Have a good day!
