Does bleach react with disinfectants containing quaternary ammonium salts?
Calling poison control first was the best thing you could do! Thumbs up!

Please note that we're usually reluctant to give medical advice - we don't want to get you or anyone in your house get killed or harmed either. 

You might want to call poison control again and/or send them the safety data sheet of the product.

The following is just additional information to give you some direction on why it is probably safe to use the mold remover on the floor previously treated with bleach.

The College of Veterinary Medicine at Cornell University has published Guidelines for the Use of Bleach. According to this document, 


  Bleach can safely be mixed with quaternary ammonium compounds that contain detergents, such as A-33 and Roccal to create a single solution with both cleaning and disinfecting properties.


So, I'd dare to say that the combined use, as well as subsequent treatment of the floor is safe, but if I were you, I would search again confirmation with official poison control rather than trusting some guy from the internet ;-)
