Q	A
Bug report?	yes

RFC?	no

• Create a simple QPR:
  
• Hit Save Button
• After the refresh, all ranges are reversed:
  

It also happens if you create CPR with PHP API.

The range is fine until the flush method will be executed here:

CoreShop/src/CoreShop/Bundle/ProductQuantityPriceRulesBundle/CoreExtension/ProductQuantityPriceRules.php

Line 401 in a5baa41

$this->getEntityManager()->flush();

Not sure if this discussion is related (Because it worked before?): doctrine/orm#11058 (comment)

If this is the case, we should sort the range based on rangeStartingFrom because the calculation heavily depends on this!
