Score sent to YouTube include spurious pedal marks

Hi, Musescorers!

Some extra pedal markings have shown up in the video rendering of my score (starting on page 2, measure 7) and I am wondering what they are doing there. Here's the video link;

On Musescore, the score can be found here:

I've checked to see if there were some invisible pedal marks in the score (thinking that the YouTube transfer somehow renders them visible) but that doesn't seem to be the problem.

It's not a huge problem, but they are annoying and I'd like to find a way to remove them. Any one have an idea what is going on?

Thank in advance!
