All dropdown lists updated instead of the one I want

Describe the problem.
I am trying to change the number of table rows that is shown in the web page.
It works, but the sitemap script changes all dropdowns on the page, where most ar filters.

Url: Fonder, Börshandlade fonder, Aktier, Marknader, Portföljhanteraren | Morningstar Sverige

Sitemap:
{"_id":"dropdown_test","startUrl":["https://www.morningstar.se/se/screener/fund.aspx#?filtersSelectedValue={}&sortField=name&sortOrder=asc"],"selectors":[{"clickActionType":"real","clickElementSelector":"option:nth-of-type(3)","clickElementUniquenessType":"uniqueText","clickType":"clickOnce","delay":2000,"discardInitialElements":"do-not-discard","id":"50_rows","multiple":false,"parentSelectors":["_root"],"selector":"#ec-screener-input-page-size-select","type":"SelectorElementClick"}]}

Hi,

If you click on the Element preview, you will see that 11 elements are matched, which indicates, that the selector has to be made more specific.

This should give you the desired result:

{"_id":"dropdown_test","startUrl":["https://www.morningstar.se/se/screener/fund.aspx#?filtersSelectedValue={}&sortField=name&sortOrder=asc"],"selectors":[{"clickActionType":"real","clickElementSelector":"[id=\"ec-screener-input-page-size-select\"] option:nth-of-type(3)","clickElementUniquenessType":"uniqueText","clickType":"clickOnce","delay":2000,"discardInitialElements":"do-not-discard","id":"50_rows","multiple":false,"parentSelectors":["_root"],"selector":"#ec-screener-input-page-size-select","type":"SelectorElementClick"}]}
