Please tell me how to make duplicate custom field names?
For example, a custom Size field for the category Children's Clothing and Size (title) for the category Clothing for Men.
Ie the name Size (custom field) for 2 different categories.
Now I can not display - I write that such a name already exists

[marius-ciclistu]

use different identifier and the same name

example:
Name Size and identifier size-cc
Name SIze and identifier size-cm

[Hunter777]

Is there another solution?

You could make one Size as a dropdown that contains sizes from children and men.
