Tried the DB on the latest version and got the same error. Optimize all gave me this "create statistics...:undeclared namespace prefix"

Dear Jason,
As you already indicated by yourself, version 7.9 is a bit older, so it would be interesting if you can reproduce the problem with a newer version. You could additionally try to optimize your database (using OPTIMIZE ALL or db:optimize(..., true()) ) and give us some feedback if the problem persists.
Best, Christian

I am running BaseX 7.9 (yes I know its old but for reasons beyond the scope of this we can't just update BaseX) on RHEL 6.9.
The BaseX is not running any instance as a server but as a standalone application with its libraries being used with my java application.
I am able to add new files to the database, but when I run an XQuery I get the following output:
*error running xquery: declare namespace tr = '[query]org.basex.core.BaseXException: Improper use? Potential bug?

The query was running fine before so I know there is not a problem with the query, I have only read about the database getting corrupt with BaseX when ran in Server and Client mode.
What may be causing this problem and what are some possible solutions?
