It does not matter to me, its a small bug, but based on the system's writings, this should have been done:

system does not replace _ with space and it gives a massage

Dear @Arman,
I suppose it's not a bug, since the same behaviour is already present on code.appinventor server.
Probably the mis-understanding arises for those (like me-italian and you-iranian) who aren't of English native language. I beieve that we should interpret the instruction sentence as:
<Project names cannot contain spaces. "space_test" SHALL be used, INSTEAD, to continue>
Dear Evan (@ewpatton), please amend me, if I'm wrong.

Thanks for telling, this is my first time reporting a problem, bug or anything like this

Dear @Arman,
I believe that any comment is most welcome by the MIT staff (I'm only a power user).
So let's wait for their answer.
All the best !

This is actually a regression in the current release. In previous versions of App Inventor, the new project dialog would accept the string and substitute the name accordingly. Thank you for the report @Arman. I have passed it along to one of our team members.
