Server is configured with a Simulation Distance of 5.
If a player opens the settings menu it displays a Simulation Distance of 10.
Using a chunk-load detector redstone circuit I can verify that it is working correctly, and that this is just an issue with the display on the settings screen.

This may be a Linux specific error. I've not been able to reproduce on Windows 10 or Windows Server.
I'll try to find some time to build a Ubuntu VM and test that. Were you using 18.04 or 20.04 (or something in between)?
My apologies for the slow reply, this is using Ubuntu 18.04.
I suspect it may be an issue with using an odd number specifically, but due to significant user access with the new update I have not had a time where no-one is online to do testing with other simulation distance settings to see if it occurs for all or only odd numbers.

I have just identified that this also happens in single player, so will be a client-side issue. I will recreate the ticket as a client-side issue after I have done some more testing.
