Multiple doubts with Responsive HTML5 Published output?

I have added Con refs in multiple topics linking child topics to parent topics while creating a user guide. I am encountering multiple problems while publishing responsive HTML5. My questions are as follows:

1. In framemaker 2017 when i publish as Responsive HTML5, only 13 to 16 topics show in side bar navigation, even though i have more than 60 topics in my ditamap, but on searching for content all the content is available?

The adobe support team could not figure out why the above was happening, escalated the issue to product team and asked me to download the framemaker 2019 and use the trial version to publish.

2. This error came in both framemaker 2017 and 2019. This time i published with framemaker 2019, the Con-refs in parent topics were displayed 2 times, even though they have been added only 1 time.
