I've set up a alphanumeric autocomplete select custom field in a data group that allows multiple records. 
When I try and post to add new values it won't accept the value for alphanumeric autocomplete-select list.

Please correct the following errors in the form fields below:
    * Please select valid custom value.

If I use the multiple choice options as basic select list the form submits okay.
