Character Sheet Stuck

So recently I was making a character sheet for someone using the 5e character sheet and was walking them through the process when I accidentally loaded up the level 1 charactermancer instead of the level up one. The issue I'm having is that I'm stuck on the review screen with all of the areas blanked out and no way to switch to a different page, when I try to press the back, back to top or apply changes buttons nothing happens. I was wondering if there would be some form of fix for this other than making the character from scratch? Thanks.

There is a workaround to exit the charactermancer by going to the A&A tab, finding&editing a attribute that's named something like "mancer-step" or "charmancer", and setting it to "0" or "off". Or you had to add an attribute with a specific name & value to exit/turn it off. Don't remember what the attribute was, but couldn't make it happen with a few tries now, so might be the trick stopped working.
