BUS combine over hierarchy

I make hierarchy like below

  1. Root

TEST_BUS2

TEST_BUS2_Sheet0
TEST_BUS2_Sheet1

It is same schematic between ‘TEST_BUS2_Sheet0’ and ‘TEST_BUS_Sheet1’

Each Sheet have two signal (TEST_BUS[1…0]) and combine this signal at TEST_BUS2.

I expect connect
TEST_BUS0@ROOT and TEST_BUS0@Sheet 0 (R17 and R21) and
TEST_BUS2@ROOT and TEST_BUS0@Sheet 1 (R19 and R23).

By the net list, R17 and R21 is connected, but R19 and R23 is NOT connected.

I think I have to something at TEST_BUS2, but I can’t find this solution.

Can you help me?

I don’t know the answer yet. Can you share your file? It would help.
I suspect that the problem is in TEST_BUS2.sch. I would try renaming some of your TEST_BUS buses there to a different name. And I would try removing TEST_BUS[3…2] (I have no idea if this is supported), by splitting the bus manually in this sheet.
