If I deploy an overcloud with network isolation via the CLI and then delete that overcloud via UI, a second deployment, triggered via the UI, will fail with an error that networks are in use [1]. This happens because the network resources created on the undercloud neutron to implement network isolation, which were created by the initial CLI deployment, were not deleted by the UI overcloud deletion and can still be seen [2]. The bug is that the UI should have deleted these.
The workaround is to manually delete them (but not delete the control plane neutron resources) [3] and then use the UI to do the deployment. Note that you can see the UI create these resources when it does the deployment [4].
