double digit list entries malformatted header

[Rob Sargent]

Emacs 27.2, Org 9.4.4, Windows 10

When I have a list of ** headings with more than nine entries on export 
to ODT the tenth and subsequent are broken: The first letter of the 
heading is fully to the right hand margin and the remainder is on the 
next line.  There's no problem with latex/pdf nor htlm output.
