exclude regex not working?

[papiermache]

we have database with a lot of tables "ref.qbo_...." (quickbooks online dumps). I wish to exclude them, cannot get this done. Tried:

• regex: ref.qbo*
• regex: ref.qbo*$
• regex: ref.qbo*
• regex: ref.qbo*$ Nada. Any ideas appreciated, need to get this working. Thx
