Title not translated

Hi dkyndt, EBT Text by default uses Block Description field (Label), you should enable Configuration Translation to translation Block Description. Because it's a part of configs.

Then check that EBT Text block type is translatable:
/admin/config/regional/content-language

After that it should be avaible to translate block configs:

I tested it on my local site and it's working fine:

You can improve UX on your own and hide Block Description field and add own new Display Title field and make new field translatable. Then this new Display Title field will be available on block content edit form for translation. Use module Fences to display Display Title as H2 tag:

Another approach is to hide Block Description field and use CKEditor to create title in you Block Body field manually.

If you use Layout Builder, then you will need to user additional module to translate Layout Builder pages:

Thank you for using EBT modules! Feel free to ask anothing about them.
