Hello,
If you mean HikaShop override (in Main HikaShop Configuration => Display dropdown => Views), you have to know that most often views are related and works together.
And so, when we make evolve HikaShop some view change, and override don't, that's why it can leads to issue, especially if your overrided view works with data that come from an updated view.
As result, the default of an override is that you have to update your override (from the new view) in order to keep flow process.
Sorry for this return, and hope that will help you to progress on this subject.
Regards
