Hope following can help:
1: Add an application blueprint to your service designer but do not configure it with "Software packages" as you would like to implemented through option/option choices.
This will help fixing your DRO and TRO.
In case TRO doesn't work, check the fulfillment json of your option.
Change it or create a new option/option choice if there is an issue with fulfillment json.
Hope this will help.
