We are currently working on the first issue which is tooltip issue and we hope to have the problem fixed for the official SP2 release early next week.
As for the second problem you have encountered, (if I understand it correctly) I believe we have already addressed it. For your convenience I am attaching the latest build of the Prometheus suite so you can test it.
Sorry for the temporary inconvenience and do let us know if further problems arise.
