I made a quick screencast, where you see that after changing the syntax, closing the file and opening that same file again, the syntax setting has reverted.
Open the file then use Bundle → Select Bundle Item… (⌃⌘T) and switch to settings (⌘}).
Now enter “filetype”, this should reveal what sort of file types are set for the current file.
When you change via status bar, it updates Global.tmProperties, but there could be local declarations which eclipse it.
