Jigsaws of trail_ruins/buildings/group_upper are not set up properly

The input fields in the Jigsaw of trail_ruins/buildings/group_upper_1/2/3/4/5 are not set up properly, being left as the same as a default jigsaw. This makes them unable to generate naturally. However they are on the list of template_pool/trails_ruins/buildings/grouped, which means they should be allowed to generate in the original design.

How to reproduce:

1. Use command /place template minecraft:trail_ruins/buildings/group_upper_1

2. Right click on the jigsaw (there is only 1) to enter the GUI

3. One should find all fields being at a jigsaw's default state, i.e. first 3 being minecraft:empty and last being minecraft:air.

4. Perform the same check on group_upper_2/3/4/5 and find the same issue.
