Progress Bar not synced with current value

[devtechvalens]

Hello,
The progress bar is not synced with the current value that defined to the progress.
I have the scenario here-
1)The progress bar has max value 5 and current value 0, the progress start and complete with 1,2,3,4,5.
2)Then I set the progress bar max value to 60 and current value to 0.
In case - 2 the value of progress bar first render to 1,2,3,4 randomly and then start the progress to 0 again.

Is anyone knows how to solve this?
Thanks

@devtechvalens it's very hard to tell what might be wrong without a code sample.
