The technology Monastic Shrines is supposed to work on all Mongol Prayer Tents. However, it doesn’t work on the last existing Prayer Tent that is not used to research this tech.
e.g. We have Prayer Tents A, B, and C before the tech is researched. Tent A is used to research this tech. After the research finishes, it correctly works on A and B, but doesn’t work on C. (pic below)
From left to right: tent A, B, and C. Tent A researches the tech.
After the tech finishes, it works on tent A and B, but not C.
