Table scraping challenge with hidden cells

Hi,

I'm trying to scrape a results page like this example:

https://www.tfrrs.org/results/62980/m/Coastal_Carolina_Invitational/

I only need the tables in 2 columns (with class "col-lg-6")

Looking at the elements it looks like the table contains hidden cells: only data with specific class are displayed (td class="heat_4010974_4_1_75"). That is probably the reason why my scraping result is messed up:

How can I fix it and only get what I see?

Here my sitemap:

{"_id":"tfrrs_1","startUrl":["https://www.tfrrs.org/results/62980/m/Coastal_Carolina_Invitational/"],"selectors":[{"id":"element","type":"SelectorElement","parentSelectors":["_root"],"selector":".col-lg-6","multiple":true,"delay":0},{"id":"table_title","type":"SelectorText","parentSelectors":["element"],"selector":".custom-table-title","multiple":false,"regex":"","delay":0},{"id":"table_selector","type":"SelectorTable","parentSelectors":["element"],"selector":"table","multiple":true,"columns":[{"header":"PL","name":"Place","extract":true},{"header":"PL","name":"Place","extract":false},{"header":"NAME","name":"NAME","extract":true},{"header":"NAME","name":"NAME","extract":false},{"header":"YEAR","name":"YEAR","extract":true},{"header":"YEAR","name":"YEAR","extract":false},{"header":"TEAM","name":"TEAM","extract":true},{"header":"TEAM","name":"TEAM","extract":false},{"header":"TIME","name":"TIME","extract":true},{"header":"TIME","name":"TIME","extract":false}],"delay":0,"tableDataRowSelector":"tbody tr","tableHeaderRowSelector":"thead tr"}]}
