Multi-format suffix can't have a leading space.

When I edit a multi-format suffix and enter a leading space, the resulting filename does not contain the leading space. e.g.

The result is always mysongmaster or mysong16bit master. All the suffixes have a leading space.

Try to use eg. a leading dash “-”

That works fine…

What’s the point of using a dash??? Makes it easier to rename with Finder/Explorer??

This is just solution for your case, to have more readable names, until this is fixed in a future update.
