With season 4, I believe what happened is that towards the start of production JMS was told there would be no S5 after all, so he put all of S4 and S5 into S4 ... but then there was an S5 after all!

In the end, season 5 was given the go-ahead, and so now season 4 seems rushed needlessly.
(History repeating itself, and Babylon 5 being cursed to ironic timing, the WB Network and UPN eventually remerged to become The CW. A Babylon 5 reboot project development was started at The CW this decade, just before WB Discovery decided to get out of the broadcast TV business and start a fresh divorce at The CW somewhat resembling the PTEN divorce.)

This is pretty common in TV shows, from what I've noticed. It takes a few seasons for a show to find its footing.
