Table Highlighter available fields error

I add a datetime field to my view (field_ct_plus_duration)

I place it above field_ct_plus_priority

TableHighlighter says field_ct_plus_priority is:

$node_data_field_ct_plus_duration_field_ct_plus_priority_value == "2 - High
instead of
$node_data_field_ct_plus_priority_field_ct_plus_priority_value == "2 - High

When I move the datefield down below field_ct_plus_priority all is well again.
