1.15 textures broken?

So I loaded Minecraft 1.15 and when I spawned into my world the iron golem textures were glitched(they were the unknown texture, pink and black), the chest was glitched, and all my enchanted tools were glowing red. I looked at the resource pack and I was using the default one but it said the default one was incompatible and so was programmer art. I put on programmer art and the chest and the iron golem was fixed, but my tools still glowed red, and my enchanted shield with a pillaged banner on it was black and did not glow. How do I fix this? Why is the DEFAULT texture pack broken? Minecraft, please fix this.
