Are purchase orders in Stocky affecting my average COGS?

[Danceman1]

I think I"m doing purchase orders wrong but have enough time to fix it.  QBPOS COGS are set at average COGS that adjusts as each voucher was received.  I've started doing some Purchase orders in Stocky and when adjusting the COG of each item to match a incoming invoice, one of the two boxes was ticked by default - the one that says "Also update the current cost price of this product variant".  

For average cost over time, I don't want either box ticked, correct?  I happen to be doing an invoice of goods that was discounted deeper to us then normal and that's going to make our profit too high for average cost?
