Mixdown Missing UR44 Bus FX?

Hello. I apologize in advance for what I am sure is a novice question and thank you in advance for any help from the community. I have recorded a vocal tracks with an instrumental on Cubase Pro 9. I am quite pleased with the results thus far with the effects from the UR44 FX Bus. However, when I perform the mixdown, the final product does not include the effects within Cubase and sound “dry”. I have tried sourcing help through the manual and research from the internet. However, no luck thus far. Hopefully, someone above my knowledge level can help. Again, thank you in advance!
