User defined playing techniques messed up after update

After updating from v. 3.5 to 4 I experience that my user-defined symbols in my “template file” are messed up - it looks like the spacing in combined symbols is ignored.
Is this an issue I can expect will be handled sometime in the future or should I simply start building a new “template file”?
I also fear what will happen if I open projects based on the template - almost all my works since v.1 is based on that template.
See the issue in the attached screenshot.

Please see this earlier thread:

Sorry for the inconvenience caused. Don’t edit these symbols to try to make them look as they did in Dorico 3.5 again – that will only compound the problem.

Thank you for the quick answer - I will wait for the fix.
