Okay, its solved – same problem like here:

Yesterday the field was not displayed to me. I have deactivated plugin, activated, page refreshed… And now its works: probably “only” a cache problem
Hello Tobias, thank you for the answer. If you are using a core function here and there is no alternative, I will have to think of something else. Maybe the plugin PHP code in table cells can help me. However, I would first have to prepare the telephone numbers in Excel and chain some PHP/HTML snippets here.
Thanks anyway, greetings to MD.
