SSE stage in brawl stage help

[pinkprincess]

hiii,
i've been trying to make a stage on final destination with the one of the parts of the forest stage in subspace emissary but i've run into trouble and haven't been able to figure it out and was wondering if anyone knew how to fix it
Okays the first problem is that two of the blocks don't show up in the stage as shown below

and this is what it looks like in collision editor in brawl box which is shown below


and uummmss.... the second problem is the water isn't like water cause like people don't swim in it they just fall right through the water as shown below


here's the pac download if anyone wants to check it out: http://www.mediafire.com/?vznjynjfzli
Andd also it goes over final destination
alsooo thanks in advance :)
