Hi @matekk,
Thanks for the post.
I am afraid this is a current limitation in ACF.
To get this functionality, you will need to ensure that all options field names are unique and thus the field name will become the “option_name” value.
All the fields in the different options page will thus have unique identifiers. This will safeguard against the the wp_options table entry becoming too long. It has a limit of 64 chars.
