Yes, they are fillers so the array of guard names can be indexed with the guard type directly.
I could quite easily rewrite the editor to subtract 2 from the guard type before indexing. Then I could remove the first two (bad) items.
Somehow I didn't think of this back then.

Another possibility is that these 'bad' bits are used in the original game, but in unused rooms (that may or may not have actual guards in them).

Not because of that.
I probably just didn't know which was the last valid guard type.
I guess I should remove these bad items as well.
