language short codes [:en] not resolved

Dear tribulant team,

We are running a multi-lingual site with WPML. We facing a problem with language support on the newsletter subscribe form. Fields are configured for English and German language, hence, fields have the format [:en]Email Address[:de]Email Address. In the current version Newsletter 4.9.5(lite version) on WordPress 6.4.3 the language short codes are not resolved and instead values for both languages including the short codes are shown. It seems your demo site (WordPress Newsletter plugin – Online demonstration of the Newsletter plugin. You may log in with demo / demo (tribulant.net)) is affected by the same problem.

Is there a fix for this problem?
