Got stuck at this part of the superbadge and do not see any solution in here.

Challenge Not yet complete... here's what's wrong: 
Create custom text fields called Question and Answer. The Answer field must allow reps to include images and format text that they enter.






As far as I can see all seems to be working, only in Chrome the I am unable to add an image, but in Firefox and Edge it works without any problem. However when I check the assigment the error still comes up.

Someone have an idea what is going wrong and how to solve it?

Thanks in advance!!
