WHen reviewing a Canvas inside a project

It doesn’t load the project in the upper right corner… if I open the BMC for Project A, thos fields should be preloaded with that info

what is the purpose of those buttoms in the upper right corner… if I open the BMC Canvas for project A… ¿what is the idea of being able to select a different Canvas? if I do so, either shows the same BMC Canvas or the page crashes (crash is more frecuent when used on iPad Chrome app).
