New Calendar issues

I was trying to create a new calendar but in the section where ask "Category used if none exists for an imported event?" I can not get any category list even if I have made a 5 categories. The software used to work without issues. So I created manually (database) the new calendar but now all the other calendar information is showing in the new one.

Could you help me, please?

Thanks
