tfs mapping URIs don't match

I share a solution with other on tfs, and have successfully mapped a local copy it to one computer. When I look at the successful mapping it goes sort of like this:

$/  C:/MappedFolder

$/Tool  C:/MappedFolder/Tool

$/Tool/ASK   C:/MappedFolder/ASK

etc.

However, when I tried using the same mapping scheme on the local computer I can't open any project in the solution. Each project tries to open a kind of nested path

e.g, for the Ask project, it tries to open

C:/MappedFolder/Tool/ASK/Tool/ASK/file

instead of

C:/MappedFolder/Tool/ASK/file

I've tried mapping several times and changing mapping through file menu, but still get the same problem.

Thanks for your help, please let me know if you need any more details
