Good Good!

Anyone having this issue also?
Two of my labs can't work. The test cases are passed but would not submit, rather returns "Your solution failed to pass all the tests". But it shows "All 3 tests passed
Total Specs: 3 Total Failures: 0"
when I click "test"

I've tried all possible debug, but no success.

Any help
The labs are:
"is_isogram" and "shopCart"

Thanks in advance
