Since generations logicians have called sentences
which you clumsily call "not a truth-bearer",
simple called "undecidable" sentences.
A theory is incomplete, if it has undecidable
sentences. There is a small difference between
unprovable and undecidable.
An unprovable senetence A is only a sentence with:
~True(L, A).
An undecidable sentence A is a sentence with:
~True(L, A) & ~True(L, ~A)
Meaning the sentence itself and its complement
are both unprovable.

~True(L,x) ∧ ~True(L,~x)
means that x is not a truth-bearer in L.
It does not mean that L is incomplete
