I have created 2 custom taxonomies and have them being used in a cloneable group in my custom post type. I can set the values, save the CPT, and when I later view it again, other values in the group display, but not the taxonomy values. I checked in the database, and the values are saving, they are just not populating the fields when the CPT is edited. Here is the saved value in the database:
a:1:{i:0;a:6:{s:25:"exh_show_participating_in";s:4:"7766";s:10:"space_type";s:3:"114";s:8:"booth_id";s:3:"301";s:5:"items";a:3:{i:0;s:3:"108";i:1;s:3:"110";i:2;s:3:"111";}s:14:"deposit_amount";s:3:"100";s:6:"_state";s:8:"expanded";}}
space_type and items are the 2 custom taxonomies, and as you can see, they have values set.
here is a link to an image of what is displayed when you bring up the CPT to edit

I have deactivated all plugins except MB and my plugin that creates the main CPT that this is attached to, it made no difference.
Thanks,
