Hi John, there is indeed a small bug in the Classes View. It erases the root class if someone edits a triple rdfs:subClassOf owl:sameAs rdfs:subClassOf. This triple happens to be generated by TopSPIN when OWL RL is used.
Fortunately this inference is very redundant and inefficient anyway, so I have used this opportunity to deactivate it in the SPIN version of OWL RL. The new version of owlrl-all.rdf 0.9.1 is online and also attached. Please copy this into the SPIN folder of your workspace (under TopBraid) and restart. I hope this fixes the underlying problem. Note that we have never tested incremental inferencing with OWL RL, and it may not do what you want. I would rather deactivate it with OWL RL. I have also fixed the more general problem with the Classes view for 3.4. Thanks for your patience and issue report.
