'Terms & Conditions' and 'Terms & a m p ; Conditions' duplicate keys in en_us/Vtiger.php global language file
I found some duplicates (again). In this case the duplicates are in key array, becasue " & a m p ;" entity is the same as "&". See linie 613: 'Terms & Conditions' => 'Terms & Conditions', linie 645: 'Terms & a m p ; Conditions' => 'Terms & Conditions',
There is also duplicate for translation with another key. 'LBL_TERMS_INFORMATION' => 'Terms & Conditions',
