Short answer: global variables used all over the place.
Slightly longer answer:

sub expand_create_data_form{
($expand_crd,$mess)= _;
               $expand_crd->set_label('Hide Create data');
               $dframe=(&create_data_form);       <===== global
               print "Added $mess\n";
               return $expand_crd;
               $expand_crd->set_label('Show Create Data');
               print "Removed $mess\n";
               return $expand_crd;

the global $dframe gets assigned the last data_form you created,
e.g. when you expand on tab #1. But then you try to remove the same $dframe
when un-expanding on tab #0 afterward, but it isn't a child of
$expand_crd there.
You somehow have to remember the "correct" $dframe per tab.
