SRDs can be generated for Service Offerings and also for options in CLM.
When users request a new service offering (in CLM 31 at least) and hit browse they see only the SRDs for service offerings, which is what they expect.
However, if they click on the "Cloud Services" category, then they see all the SRDs, including option SRDs. This is particularly likely to happen if they have chosen a sub-category and then want to go back to the top-level "Cloud-Services" category. This then obviously causes confusion as they suddenly see a lot of service offerings that they do not expect.
If they click on Browse, then it only displays the service offering SRDs again.
CLM should ensure that clicking on the "Cloud Services" category has the same effect as clicking on Browse (i.e. no option SRDs are displayed).
