If I understand you correctly; I believe this is where the problem is:
Macros and Insert LF Key Equivalent ⌘ ↩
You can get to this using this shortcut: ^ ⌥ ⌘ K to open up the list of keyboard shortcuts (this only shows bundles that are active). Select Source in the bundle drop down. Macros in the middle.
I believe this handles that key sequence in all (most?) bundles. If it's different then you can modify it in the bundle editor.
if you meant ⌘⌅, I only have that in Markdown, and it selects part of a line (an item, s).
Hope that helps.

What I mean is, when I hold the command key, nothing happens except the the little *dunk* sound that means "you can't do that."
Previously it would drop down a line (like downarrow) and insert a new line.
