Analysis Error - 'The code rules selected in Rule Set "Frequent Service Design" do not appear compatible with the load factors in the load combinations using the rule set. This is likely an error'

Hi, 

I am working on a Mat Foundation Raft to Eurocode 2 in RAM concept and have input all my own load cases and load combination (approx 100 different cases).

When I try to run this I get an error for all the rule sets saying that my load factors do not appear compatible.

All my loads have been put in as load type 'Other' except the defaults (self dead loading, balance loading and hyperstatic loading)

When I set up my load combinations I have selected them all to include all 'plans.'

What is likely to be causing these errors and if the load combinations I have put in are 100% correct does this error actually have an effect on my model output?

Regards,
