I have default field Account type (dropdown) and custom Type_c (dropdown) in Account module. The dropdown isn’t the same.
But it seems like both fields have the same libel.
In Studio->Account->labels I have only one label LBL_TYPE with value Account_type (or other if I change either of the two fields)
Yes, both fields have the same label definitions.
Do change System label of your custom field from database table fields_meta_data and change the name of your custom field to LBL_TYPE to LBL_TYPE_C or whatever you call it and add that label at
custom/modules/Accounts/language/en_us.lang.php
added LBL_TYPE_c in custom/modules/Accounts/language/en_us.lang.php
renamed LBL_TYPE to LBL_TYPE_c int custom/modules/Accounts/metadata/edit and detail views
QRR
went to studio->accounts>field->selected and renamed Display Label for my custom field
it was renamed but after my first rename it was change yourself System Label from LBL_TYPE_c to LBL_TYPE_C and added LBL_TYPE_C in custom/modules/Accounts/language/en_us.lang.php
So at this moment label changed LBL_TYPE_C
Where I can edit this moment? I mean stoping converting LBL_TYPE_c to LBL_TYPE_C after first change in studio->accounts>field
