Grading page filter does not shows results as expected

Hi friends, on the grading page I add min and max grades but the result shown not expected,
Please see the screenshot I attached, I would like to know, What is the matter with those results being shown like this? Thanks in Advance!

Hi @Shukurlu! What version of Open edX are you running, and where is it hosted? If you can share logs or any additional information that could help community members assess the issue, please do.

Thank you much for your comment!
We are using the Maple version,
And I don’t know actually there is a logic behind the filter that it shows like this or properly it doesn’t work
