Quiz data transmitting to LMS out of order

Hello,

For a project we're working on, we had questions that were transmitting data to the LMS as "undefined." We realized it was due to the answers beginning with a dollar sign ($) and so we corrected that. But since we corrected that, the data for these 2 questions is getting dumped at the end of the report we're running from the LMS instead of where they belong in the order. 

As as you can see from the attached screenshot, the questions should be in the 2nd and 7th places in the data, based on where they appear in the course, but are actually showing up in the 11th and 12th positions, respectively. 

Has anyone encountered a similar issue? The only thing that changed was removing the $ from the answer choice. 

Thanks,

James
