What I expected: A chest next to an enderchest would generate in a certain room of end city.

Actual result: No chest and enderchest in a room where it is supposed to generate (see pictures below), but the 2 chests in the room with a parkour staircase filled with shulkers and the chests, item frame, and elytra, still generate (all in same end city).

Steps to reproduce:

1. Go enter end
2. Go to outer end islands
3. generate end cities in either 1.14.60 or 1.14.30. 
4. Go to room in picture below
5. The chest and enderchest would not be there, although all the end rods, all purpur, glass panes, and ladders are still there.

The pictures below is what it is supposed to look like. I am unable to take pictures of room without chests generated.
