There have been some recent changes to the character sheet framework. My guess is that some of the recent changes broke those built in chat menus due to the use of html replacements, which is probably not necessary any longer. You might want to try contacting one of the sheet authors directly. If I have pulled the Roll20 account id correctly from github, this is a link to one of the authors of that sheet: <a href="https://app.roll20.net/users/1164773/karl-h" rel="nofollow">https://app.roll20.net/users/1164773/karl-h</a>
