Constant Server PDT Errors due to Glitch in Block Data

Recently, the server console has continually spouted out a series of error messages such as this one:
[Wed, 27. May 2020 19:29:54 PDT ERROR] Block at -12, 30, 192 is Block{minecraft:barrier} but has [email protected] Bukkit will attempt to fix this, but there may be additional damage that we cannot recover.

It prints out several of these every few seconds, causing considerable server lag, and general annoyance.

I am running a paper server (version 1.15.2-R0.1-SNAPSHOT, latest update as of the time of posting.

I have multiple worlds linked using multiverse, and I am unsure what world the error message is referring to or what I can do to fix it. Any help would be greatly appreciated!

Good afternoon, do you use ViaVersion or ProtocolSupport?

With kind regards
