Bug copying profile in CiviCRM/Joomla

Question

I was just trying to copy a profile in CiviCRM 5.12.3 and Joomla 3.9.5 and am receiving an error message.

An error has occurred.

0 @import url(/administrator/components/com_civicrm/civicrm/css/civicrm.css); @import url(/administrator/components/com_civicrm/civicrm/css/crm-i.css); @import url(/administrator/components/com_civicrm/civicrm/bower_components/font-awesome/css/font-awesome.min.css); Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred. is not of type String

Return to home page.

function toggle( element ) { var parent = element.parentNode; var className = parent.className; if ( className == 'crm-accordion-wrapper collapsed crm-fatal-error-details-block') { parent.className = 'crm-accordion-wrapper crm-fatal-error-details-block'; } else { parent.className = 'crm-accordion-wrapper collapsed crm-fatal-error-details-block'; } }

After the, I see it created a new profile, but it creates only the first field. I have tried the default profiles as well as ones I have created.

Any one see this before?

Thanks, MikeM.
