Hi,
Sorry for such a late reply – I’ve just got back to the office today.
Regarding your request – actually I believe it’s an issue with your theme. I’ve just tried adding a field on my test server (with the Storefront theme), and it seems to be working fine, last line is not overlapping with the description – please check this screenshot.
As I understand, you are adding a “Textarea” type field, correct? If that’s the case, could you please try changing the type to “Text” – is the problem still there?
Also, if you wish, you can send me the link to your theme (or zip, if it’s a paid one), so I could test it on my server (my email is [email protected]).
