First time merge glitch user

[DuMularn]

I started working on a park a few nights ago. So far it's going really well. Beautiful indoor park that brings the outdoors inside. I wanted to start out and lay down my framework/main area without the merge glitch to ensure smoothness and then pop the glitch on to fine tune some details (stairs, bowl, wiring on the wall, etc). However when I went to go use the glitch I found that I can't acces my DLC with it turned on and in turn can not edit my park. Is this a common problem that someone can walk me thru? Am I S-O-L and just have to complete this with no glitch? Should I be looking for someone who can use the DLC with merge glitch to finish off my park?

UPDATE: I moved this from further down in the post to help make it easier for everyone to see

Here are a few pictures for you guys. I need a tester or two to check all my obstacles. I feel I've done a good job testing it...but you never know how people will use what you made differently. Anyway if anyone is interested in testing it for me let me know and we'll work it out. Also I might be in the market to join an online team so I can share my park when it's complete. Apologies in advance for the picture quality.
