Every time you change the quantity, Sage recalculates the pricing (according to the pricing hierarchy), which could include pricing breakpoints for different quantities.  This is normal and cannot be disabled.  (We've done scripts to basically capture and restore overridden pricing, but that is not available without customization).

If the result of the recalculation is zero, then your item prices should be reviewed / corrected.

Unit price drops down to 0 when changing the quantity of "ordered" on the same line item. Is this normal behavior, or was this intentionally implemented at some point? Can anyone point me in the direction of an article to reverse this?

I have a same doubt but today i was see this post and find my answer is here...  McKesson Connect
