Pagination breaks after first page

I am new to Web Scraper and have been through a fair amount of the pagination problem posts here, but cannot find any similar.

When manually stepping through the site map the data extract works with the element click pagination. When scraping it however breaks after first page. Can anyone help?

Url: https://www.morningstar.se/Funds/Quickrank.aspx?sort=FundName&ascdesc=Asc&view=returns

Sitemap:
{"_id":"morningstar_avk","startUrl":["https://www.morningstar.se/Funds/Quickrank.aspx?sort=FundName&ascdesc=Asc&view=returns"],"selectors":[{"id":"paginator","type":"SelectorElementClick","parentSelectors":["_root","paginator"],"selector":".rgMasterTable tbody tr","multiple":true,"delay":0,"clickElementSelector":"a[title='Nästa']","clickType":"clickOnce","discardInitialElements":"discard","clickElementUniquenessType":"uniqueText"},{"id":"rowrapper","type":"SelectorElement","parentSelectors":["_root","paginator"],"selector":".rgMasterTable tbody tr","multiple":true,"delay":0},{"id":"fund","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"a","multiple":false,"regex":"","delay":0},{"id":"nav","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(4)","multiple":false,"regex":"","delay":0},{"id":"currency","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(5)","multiple":false,"regex":"","delay":0},{"id":"today","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(6)","multiple":false,"regex":"","delay":0},{"id":"lastweek","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(7)","multiple":false,"regex":"","delay":0},{"id":"lastmth","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(8)","multiple":false,"regex":"","delay":0},{"id":"last3mths","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(9)","multiple":false,"regex":"","delay":0},{"id":"last6mths","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(10)","multiple":false,"regex":"","delay":0},{"id":"thisyear","type":"SelectorText","parentSelectors":["rowrapper"],"selector":"td:nth-of-type(11)","multiple":false,"regex":"","delay":0}]}

The pagination won't work on this page as with most .aspx sites due to their structure.

Ok. Strange that it works when manually stepping through the site map.
I also got it to work under OctoParse, problem there is that it is extremely slow.
