Field name 0(Zero) doesn’t save data and Field Label 0 isn’t being displayed. I looked closely and found out Field name ‘0’ doesn’t have data-name attribute.

Field name 0 after saving in the selected location or taxonomy:

What can be the problem here? I have been using ACF Version 5.9.0. Thank you.

I don’t know the exact cause of the issue, but it’s never a good idea to have field names start with numbers. When labels need to be numbers I will generally alter then field name to something more significant like size_00 etc.
