Hello Owen,
Seems you did not configure token for all nodes correctly. See the section
Calculating Tokens for multiple data centers here

Best regards

We have a 2 data center test cassandra setup running, and are writing
to it using LOCAL_QUORUM. When reading, sometimes the data is there,
sometimes it is not, which we think is a replication issue, even
though we have left it plenty of time after the writes.
We have the following setup:

Does anyone have any ideas why every server does not have the same
amount of data on?
Thanks,
