two questions first:
1. are you sure this water isn't condensation, a common issue with hybrid and popup canvas ends?
2. did you follow the canvas manufacturer's instructions and wet the tent seams down and then let them dry, before going camping?
these are much more common causes of water in the tent ends, that what you're describing. not saying that yours isn't from something else, just trying to eliminate the more common causes.
