We're having trouble with the "Extending Reports using the AppExchange" module in Trailhead

We keep getting the same error when checking the challenge at the end of the module:

Challenge not yet complete... here's what's wrong: 
The 'LEAD Trend by Source' dashboard component does not have the wedges set to 'Lead Source'.

Wedges ARE set to 'Lead Source', did anybody get this error message? do you know what the solution may be? Thank you!

It's two of us taking the challenges in Salesforce Trailhead. We are being able to complete all of them succesfully except for a couple. The first one we are having trouble with is the challenge in the "Using the Report Builder" section. We keep on running into the same error over and over again, we've tried everything but we are not able to move on. The error message we get is the following:

Challenge not yet complete... here's what's wrong: 
Please check that you have a filter for Amounts greater than 25,000.
 
We believe our filter logic is correct:

Filter Logic:1 AND NOT (2 OR 3)
1. Amount greater than "25000"
2. Stage equals "Closed Won"
3. Stage equals "Closed Lost"

Has anybody run into the same problem? Do you know what the solution is?

Thank you!
