german language file

First: I need german language for the component Table JX . The language overrides don`t work!?
Second: Im not able to change the Frontend layout to other than Table JX.
This options:
Card JX
Graph JX
Record JX
are not chooseable.
Third: I paid for the component but I don`t want the "Powered by Tools JX" under my table.
It would be a good idea to have a possibility to switch that off in the backend. Please let me know where I can switch it off!
Thanks in advance
