LMS output request method, POST and not PUT

Hi,

I'm hoping if anyone can help me with our issue. I brought forward an older Storyline into 360, and published as TinCan/HTML5 only.

However, our Programmer noticed, the  method published is PUT, instead of POST

Our LMS only receive POST request method

My question, is there any options within Storyline to publish the method to POST

I've attached a screenshot of our issue.

Note, we could rewrite the code to accept PUT, but that's not our first choice, we would hope to make the change in Storyline output, if possible. 

Any help would be greatly appreciated!
