Metanode doesn't show output table to connect metanode to other nodes

Usually when i group nodes into a metanode, i can then connect the output of that metanode to other nodes downstream. For some reason, this one is not allowing me to. It shows a plus sign to the right where i normally would connect the output to another node.

When i expand the metanode, i’m able to run all nodes within it successfully and there’s an output at the end. What else could cause this issue?

Metanode

You ma need to add output port.
