You can find the view at src/pages/Shelters/View.jsx that handles /shelters/XXX.

I took a quick look at this, seems like the response from the graphQL query doesn't have any batches in it despite there being some batches for that shelther. Could be an issue in the query itself or some bug in the backend service and/or caching.

Please do note that not all shelthers suffer from this, for example /shetlers/236 works just fine.
