I have looked into it further, it is a bug in the move-to-column
function
in XEmacs that does not behave well in combination with hidden text,
when the FORCE argument is given.
Maybe you can try to write a replacement that will work?

Hi.
There is some problem with tags and headings. I've had instances where
the tag has disappeared or merged into my heading.
Repeatable with Xemacs 21.4.19 i586-pc-win32, org 5.22a using this
fragment:

If i try to add the S into the heading when it is folded, then it
generates the error "Visible portion of buffer not modifiable".
Debugger gives:
