CS50P Check50 not working (Pset 3)

[youssefelmarasy1]

I completed the code for the "outdated' problem in Pset 3 and I successfully passed all test cases except for one. When I manually tested the output that should be given, I found that it's correct and that check50 checks it wrong.
In particular, the check50 function gives me this:
"input of " 9/8/1636 " outputs 1636-09-08
Did not find "1636-09-08" in "Date: ""
When I tested the input, which is 9/8/1636, I get the correct output, which is 1636-09-08.

Is anyone else facing the same issue?

Right After using check50, I put in the input for the "failed" test case and it worked as shown below

Actually it's because the prompt send by the check50 have space around, it's hard to find out
