[SOLVED] PHP Warning and language problem -> field's name

Hello.
I don’t know if the 2 problems are related.
The module seems to use the plg_flexicontent_fields_coreprops plugin to display the main category.
There is a PHP warning of an undefined variable on line 138 of the file/plugins/flexicontent_fields/coreprops/coreprops.php and the text "Category (main)" is not translated, nor when I use the language substitution system with the string FLEXI_COREPROPS_CATEGORY_MAIN (in admin + frontend).

Solution : it's not a language string, it's the field's name.

hello display warning is'nt a good etting for production site go to global config and set error reporting to defaut

Thank you. This website is in development. I'll put error reporting to defaut on time.

ok

and for "Category (main)" how can I translate this text that remains in English? What is the language string please?

Edit your field and change label
