SR 1.8.3 (german) Frontend - Translation problem in "Guest info & Payment"

Dear SR-Team,

i found a translation problem - (attached image)

using the original 1.8.3 translation files @
/components/com_solidres/language/de-DE/de-DE.com_solidres.ini

I've found all translations for the corresponding strings - most of them (Name, Adress Country) in line 26 to 41
other as VAT somwhere but they're there -
not missing but "just not" working ???

I've double ckecked with the english translation file (en-GB.com_solidres.ini)
everything seems to be ok ... s

Do you have any idea where the problem is ?
thanxx!

Hi,

If you are using Custom Field plugin, then you need to translate those fields in Solidres backend - Custom fields or with Falang, not via language files.

Regards,
