Engine COMP extensions issues

The extension parameters are there, so i tried but to create an extension for an engine COMP via the customize component, but I get an error:

File "/sys/TDDialogs/CompEditor/extensions/ext2/addMenuExec", line 8, in offToOn
File "/sys/TDDialogs/CompEditor/CompEditorExt", line 571, in AddExtension
td.Error: Invalid number or type of arguments. See help for details. Value:(<class 'td.textDAT'>, 'sdf') Type:<class 'tuple'>.

If i specify the extension manually it doesn’t seem to be loaded when I hit init, but when I use the new ± buttons to add additional extension objects, then my intial extension is loaded
