The other one just stay tight to the rim, and I'm able to put the tyre whiteout any problem.

Also I have to admit that the tubes are never used.
Can be fixed in any way?

First put the tube in the tyre, then put the tyre on the rim. It may take some manipulation to get the "extra" bit of tube to lie flat, and you have to be careful not to damage the valve stem.
