UR-Node Acess fails with multiple relationship types

I create a relationship type called "friend". (For simplicity let's say it is two-way and does not require approval, but it doesn't make a difference.)

I create three users, Alice, Bob, and Charlie, allowing them to create content, have and maintain relationships, and grant view permission to related users.

Alice creates a node called "Hello all", without checking any boxes in the "Post to social network" options, which makes it accessible to all users. So far, so good. Bob and Charlie are now able to access that node.

Alice sets Bob as her "friend". Then Alice creates a node called "Hello friends", checking the box to grant view permission only to friends. Again, so far, so good. Now Bob can see both of her nodes, while Charlie can only see "Hello all."

Now I add another relationship type: "associate". Alice sets Charlie as her "associate."

Now there is a problem. For some reason, Bob has lost access "Hello friends", but he can still see "Hello all".

If I delete the relationship type "associate", Bob is once again able to access "Hello friends".

This behavior occurs even if both relationship types are created from the onset.

This has made it impossible for me to use UR-Node access at the same time as multiple relationship types.
