想请告诉你，这里contains是名词吗，containment才是名词吗？假如contains是名词

While planning the organization of your items, remember that clutter distracts the customer and actually displays less in contains less items.

While planning the organization of your items, remember that clutter distracts the customer and actually displays less or contains less items.

【翻译】在规划组织你的项目时，请记住，凌乱不堪会分散顾客的注意力，而且事实上，那样展示得更少或者包括的项目也更少。

我感觉，contains 是动词，跟前文displays 并列，之间不可以用介词in，而应该用并列连词 or，才对。
