The Bonide's Fog RX Insect thermal fogger that you purchased with the CSI 4-4 has very specific products it lists in the manual that can be used with it. Professional grade products like the CSI 4-4 are not recommended to be used in it as issues can arise as you have experienced.
We do state on the product page the following:
Pictures of bottles on the Fog RX box above are recommended products to use with this fogger
