UI does not show 'skip header' option when manually providing schema
Steps to reproduce:
1) Start creating a feed
2) Choose the option to manually provide the schema in Step 3 of stepper. Note that there is no option to skip header.

3) Complete creating the feed. Go to feed details. The skip header option is available for editing here. By default it is ticked 'yes'.

So, by default, the header will always be skipped when manually specifying the schema (unless the feed is edited and option removed). This may lead to errors/loss of data when processing the actual data files via the feed.
