P&L pivot table: combinations of styles do not work

[hewemel1]

In my P&L pivot table in Qlik Sense Enterprise on Windows , combinations of style specifications like in 'MyKey;<bold>;<italic>' do not work. Each individual style like in 'MyKey;<bold>' does work. What am I doing wrong?

An example is enclosed as QVF-file. And here is a screenshot of the sheet with the data and the result.
