stuck with my tagFormat config again

[aliasname]

Hi mates, haven't played with Minimserver since some time.
Looks I was lucky enought to update prior to running into -107 problems.
But I got stuck at another thing.

my TagFormat worked ok with the folling configuration:
artist.displayformat\={$albumartist^}, album.displayFormat\={$album^$albumsubtitle^ [^] $Date$AlbumVersion$ReleaseYear^ <^>^ }, title.displayformat\={$tracknumber^^. $title^$subtitle^ [^] $version^ <^>\#AudioData^ }

but not can't get it running.
Error is "incorrect optionname 'displayFormat\' in property tagFormat

any idea what happened?
For better understanding .. worked with MininServer running on Win10 ... not I tried Minimserver on my NAS, but I bet that shouldn't make much of a differnce?
