Issue Description

Some (but not all) of the Additional Banners patterns- for example, including the Cobweb and excluding the Anchor- show up as a black and reddish checkerboard when applied to the flags added by the Supplementaries mod. (Please note that Supplementaries is currently still on 1.20.1, so I am using relatively-outdated 1.20.1 versions of Bookshelf and Additional Banners. However, I did not see any indication in the patch notes for later versions of Additional Banners, or on this GitHub bug tracker, that this issue was reported or fixed, so I decided to go ahead and report it anyway.)

I initially encountered this bug on a heavily modded world, but when I attempted to reproduce the issue on a new MultiMC launcher instance, with only the four mods in the "Mod Version" field installed, and no resource packs at all (not even the built-in Programmer Art), the same glitch occurred.

I know basically nothing about coding, so I don't know if Additional Banners or Supplementaries is causing the bug; but I plan to also report this glitch to the Supplementaries issue tracker.

Some screenshots I took of the issue are provided below.

Hello, thanks for reporting this issue. It looks like Supplementaries adds support for Additional Banners on their end, so you should report this issue to them.
