endif errors in editor?

I tried to open a map and i get these endif if errors. Is there any way to get rid of these errors, like editing the war3map.j or war3map.wtg? Maybe a program?

Maybe there are errors in the custom script or in custom text triggers, then you can fix them there, or it are map editor bugs, then I don't know what's the best thing to do.

if you used complete GUI, then the error might be with using the Get effect/sound of ability calss which are bugged in GUI

So how should I go about fixing this?
