Selecting a build as a parent and deselecting it as a child doesn't work

I made a mistake setting the dependencies for the IE Selenium Build. I accidentally set the JIRA Func Tests Build to be its child build, instead of its parent build. When I went back in to update it I selected the JIRA Func Tests Build as a parent build and deselected it as a child build. When I saved the changes Bamboo complained that I had created a circular dependency and didn't deselct the JIRA Func Tests Build as a child build.

In order to make it work I had to deselect the JIRA Func Tests Build as a child build. Save changes. Select the JIRA Func Tests Build as a parent and save changes.

Not a serious issue but kind of annoying
