Basically, if I remove the first [ from the tag provider and include the % it works, with the bracket and with or without % does not. I copied the value directly from the table so I know it's correct.
This wasn't anything related to Ignition, rather the database, which sadly enough for my project is MSSQL. Most likely other databases like MySql, Postgres, won't run into this issue but I don't have them installed to check.
So, dropping the first bracket or doing as they suggest in these links will work.
