Yes, this is a common "fight" between people in Bosnia and neighboring countries:

In Bosnia, "börek" (or "burek", as is its local spelling) is only filled with meat, while the rest of the dishes fall under the broader category of "pitas" (or pies): sirnica (filled with cheese), krompiruša (filled with potatoes), zeljanica (filled with cabbage), jabukovača (filled with apples)...

In Serbia and Croatia, they're all "burek" with different stuffings, so burek with cheese, burek with potatoes, etc.

It's a weird hill to die on, but you will receive some weird looks if you request just "burek" in Serbia/Croatia/Montenegro, or "burek with cheese" within Bosnia.

Zeljanica is, despite its name, filled with spinach rather than cabbage. Then there's also an abomination called "pizza-burek", it's probably as bad as it sounds...
