Where user specified value disagrees with autosizing?

I have a sizing disagreement in my idf file, but I'm having trouble finding where I inputted the conflicting fields. Any ideas on where I should look? And here is a google drive link to the files.

Here is the relevant part of the ERR file:

   ************* SizeWaterCoil: Potential issue with equipment sizing for Coil:Cooling:Water LGSTORE1 ZN COOLING COIL
   **   ~~~   ** User-Specified Design Air Flow Rate [m3/s] = 0.79234
   **   ~~~   ** differs from Design Size Design Air Flow Rate [m3/s] = 0.87231
   **   ~~~   ** This may, or may not, indicate mismatched component sizes.
   **   ~~~   ** Verify that the value entered is intended and is consistent with other components.

Here is the relevant part of the EIO file:

 Component Sizing Information, Coil:Cooling:Water, LGSTORE1 ZN COOLING COIL, Design Size Design Air Flow Rate [m3/s], 0.87231
 Component Sizing Information, Coil:Cooling:Water, LGSTORE1 ZN COOLING COIL, User-Specified Design Air Flow Rate [m3/s], 0.79234

But the strange thing is I think those fields are autosized.

Not sure if these are important, but those conflicting flow rates appear elsewhere in the EIO file.

However, I think those fields are also autosized.

I would guess that the program is incorrectly telling you there is a difference in sizing values even though you have specified all fields as autosize. I suggest sending this input file to the help desk at energyplus-support@gard.com so that this may be fixed.
