1.17.1 Issue with Mythicmobs items LORE

Summary

In 1.17.1, if there are two colors in the same LORE, MM will automatically add additional &f codes

Steps to reproduce

Create an MM item just like

helloworld: Id: Paper Display:'&6HELLO WORLD' Lore: -'&aHello &eworld'

Current Behavior

There are two color codes in the LORE of the item "hello world". When the player gets the item, an extra &f is added to the item's lore. This caused other plugins to fail to recognize mm items

Expected correct behavior

The &f in LORE should not exist
