If PGE was originally made for SMBX, then why put things in it that aren't available to use?
PGE is designed to be a separate engine to replace SMBX in the far future. Right now it is a more user friendly version of SMBX level editor, and the engine itself is still in development and doesn't replicate the gameplay of SMBX very well (which you may have noticed if you ever used the alpha tester to test levels). The greyed out options may be disabled by the SMBX config packs, although I don't know if that is true.
