having issues adding my game to GP

I have a game (D&D 5e) that I would like to run here. I enter the game info, character sheet, system and writeups and click the "Create" button . . .

Nothing happens.

I've tried this with both Chrome and Edge browsers. The "Create" button is clickable, but nothing happens.

Am I doing anything wrong? Do I lack game create permissions?

What must I do to get my game on this here board?

The character sheet selection might be finicky. When you select the 5e sheet from the dropdown, did you then click the + sign beside it to actually add the sheet to the game?
