Possible Issue With Articulate Variables (Storyline 6)

Hello Everyone,

I am working on a very large course (around 310 screens), which is ended with a 35 question multiple-choice test. 

The final slide shows the users score (Your Score) and the passing score. I get the users score from the variable "Results.28.ScorePercent". I want to display it with a percent afterwards, so I did "%Results.28.ScorePercent%%". 

When I saw my initial error (see the "Passed" slide) I assumed it was because of the double percent sign at the end. However, the failed slide is the same line of code.

I think an obvious fix would be just to make it "%Results.28.ScorePercent% %" with a space between the variable the the percent sign. 

However, I never encountered this error before and I wasn't the one who took the screen shot, so I don't know what browser or OS they were using. The screen shot they sent me had no clues, but because this has always worked on PC, I am thinking they might be on an iOS platform.

I know there's some things that don't work across platforms (JavaScript, etc.) but I am fairly certain that Articulate variables do. Does anybody have any ideas on what the issue could be?

Thank you :)
