A minor help request, towards debugging Musescore

There's a bug in Musescore's web interface that I'm seeing quite consistently, which their developers seem not to be able to reproduce. I have several scores on their server which are quite short but which feature many repeats, resulting in a fairly long play duration. That duration is shown at the top left of the score, as displayed in a web browser, and should be 3:19:48.  But every browser I've tried, with a variety of setup options, on two machines at home and on one at my library, shows it as 27:19:48 -- that is, an extra day tacked on.  The pieces are monotonous, but not that monotonous..!

If you wouldn't mind, would you please take a look at: https://musescore.com/user/28554317/scores/9087566, and let me know what duration you see just above the upper left corner of the score?  (At the library, I had to expand the page to "full screen" mode with a button at the top left in order to see the duration display.  I don't know why that was different from my machines at home; it may be a matter of screen resolution.)  It might also be useful to me to know what operating system and browser you used.

Thanks!
