Backend module: Seo/Metatags not working with sys_language_uid != 0

[Domtaholic]

MetaSEO version: 3.0.0

TYPO3 version: 8.7.24

Hi,

the Backend module Seo/Metatags isn´t working when the sys_language_uid != 0.

Example: I change the title from a Page sys_languade_uid=0 and everything works as expected, i switch to language: FR in my Case 2 and want to change the title either. The change isn´t saved, network tab seems fine, reponse is a 200 and the parameters are send correctly.

Even as admin user the fields aren´t saved. Any help would be appreciated.

Cheers.
