Error when saving a form

Hello everyone!

When saving a form get the error:
“Undefined array key “exportemail_email” | Script: C:\Program Files\NetMake\v9-php81\wwwroot\scriptcase\devel\class\xmlparser\nmXmlparserApplicationVars.class.php linha: 1123”

There is no email related field or code in the form.

Also after generating the source code, when click on Close it’s closing the tab with the opened app not the code generator tab.
