If you are issued a bench warrant for a traffic violation and you pay the fines, will you still go to jail?

The violation was for suspended license and no insurance. I failed to appear, but quite some time later, I paid the fines. This got my license reinstated. Fast forward almost 6 years, I think there is no problem and I drive every day back and forth to work. I am pulled over for expired registration. The next thing I know, I am placed under arrest and taken to county jail and held in a holding cell for a whole day. They would not OR me, so I had to pay a bail agent to release me on bail. Will they throw me in jail even though the ticket is paid? I have a family and a great job now. I always had trouble in the past paying everything due to lack of decent employment with decent pay. My wife is disabled and I am the only one who works. This is my biggest fear.
