Describe the bug
Only one highlight filter can be active at any one time. Once I create a new filter that includes a text highlight, the previous filter that was highlighting text stops working (the filter still detects as it plays sound, it just doesn't highlight the line any more).

Minecraft Info
Minecraft information:

• AdvancedChat 2.1.0, Minecraft Java 1.16.5

To Reproduce
Steps to reproduce the behavior:

1. Create a filter including a text highlight
2. Test, filter should work
3. Create a new filter including a text highlight
4. Test, filter should work
5. Test the first filter you made, highlight will no longer work

Expected behavior
I expected to be able to have multiple filters working at once to highlight different categories.

Just fixed in (2.1.1 hopefully it is approved on curseforge by now)
