Error 30271 in setting static + transient SSI analysis

  Hi!
  I'm trying to set up an SSI analysis using *LOAD_SEISMIC_DECONV and *INTERFACE_SSI
  
  I have been trying to get it to work but I get the following error (this is the same error I get although node numbers might differ from mine as I got them from another example online). I don't understand why I'm getting this error. I use *INTERFACE_SSI_STATIC_ID in the static case and the same keyword without the STATIC in the transient case. I use the same sets for each. How can there be a node mismatch?
  *** Error 30271 (INI+271)
  # of nodes 4418 in SSI contact interface id 1
  do not match stored # of nodes: 890217136

  Hello
  
  We have seen your request for support in ACSS (Cust. SUp. Space) and will help you there instead (we might need to look at the specific example etc and can share files there).
  
  Thank you
  Erko
