The issues below pertain to containers from the Decorative Kitchen Set and Decorative Stable Set found in the UO Store. All of these are similar space issues to the gold, gem, and reagent bags from treasure maps that were all recently fixed.
In the China Cabinet, items can only be placed in the top left corner. The rest of this is currently unusable space. The Pie Safe (which is basically the same item with a different name) has the same issue.

Same issue here with the Feedbag. Items can be placed no further to the right than as they are seen here. Only the top left corner is usable space.
