Console Error

No response

Bug Description

When I'm alone on the server, the indicator is emulated, but when a player with 1.12.2 joins, the indicator disappears, as if it thinks I'm also running 1.12.2.

But if another player joins with the same version (1.8.9), the indicators work

Steps to Reproduce

Try logging into the Paper 1.12.2 server together.
Let's say you're using 1.12.2, and the other is using 1.8.9.
After this, the 1.8.9 indicator will disappear

Expected Behavior

I expected the indicators to work even when I'm not alone on the server

Additional Server Info

No, i use Paper 1.12.2
