Function Block not inputting the correct values

Can you post couple screenshots and exported function block.
Without more info it will be difficult to say anything
 
We managed to figure out what the issue was. For some reason when we copied the DFBs it didnt create new instances of them. So regardless of the tags into the blocks being different, there was multiple blocks called "generic_alarm_1" So internal tags were overwriting each other
