Question:
The 384 Inf XX is listed as `forming” in Oct II 43, but it is initially in the West on Jul I 43, and historically it went to the East Front about Oct II 43.

Answer:

The Oct II 43 West listing is missing a line. It should read:

West, Forming:
1 × 14-10 PzG XX 17 GvB (SS)

Withdraw to East:
1 × 5-7-6 Inf XX 384
