This does not surprise me at all.  How are you controlling the evaporative coolers?  Many 
things change when
you use an evaporative cooler (100% OA, more pre-cooling, etc.) , so you may be leaving 
the building at the lower temperature at the beginning of  the next day that then 
necessitates more heating.  I'd suggest you take a look at the indoor temperatures and 
compare them to those with a RTU.  As to what to do about it, it depends on what's your 
objective - to minimize energy cost or electricity, no increase in heating fuel, etc.  
Achieving that would
require some tweaking of the operations.
