Ultimate Membership Pro : Public individual page editor

Hi,
I have created some template code for the Members List Public Individual Page. OK. Works fine.

But if I try to modify my input, there are not saved !
The only way that I found to modify my code was to copy/paste it into NotePad++ then delete the custom content, save, open it again, paste my code, save the page !!!
