@1franka...this is not solution...

if you use the skin, you need to follow the translations.
or yes, install the version from 16 feb 2020 that worked well and stay there...
because who knows what change will be done in the next update ??

practically you need a full translation both plugins (speedcam.zip and driveralert.zip) in your dictionary.voice

if you want send me a copy from your (lang + voice) for check...
