Dispatch Script Not executing on all files selected

I have created a test dispatch script that adds three variables on group of files selected through a right click menu command option.

The dispatch has three set variables actions preceded by check out along with user prompts that populates the appropriate data card values and followed by check in

The script has the customary start block and end block for all the documents.

However, the script when run does the user prompt action for all the files individually instead of doing it just once.

What could be the reason for this behavior? or am i missing something obvious? I am new to Dispatch, so apologies for being silly here!

Many Thanks,
