Hello,

Welcome to Microsoft Q&A!

ProgressBar.Progress should be set between 0 and 1, but here the value is great than 1, it is treated as 1, this is the reason that it is filled.

Values less than 0 or larger than 1 will be clamped to the range [0-1].

Correct your code as below

   progressBar.Progress = e.ProgressPercentage/100;
