Null data when table header include /n

Web Scraper version: 0.4.1
Chrome version: 74.0.3729.169 (Official Build) (64-bit)
OS: Windows 10 1803

When using the below sitemap, data represented in web table where column headers include new line "< br >" (without spaces) isn't captured from the table and therefore output just shows "null" for each cell/row. I attempted to include "/n" and "< br >" in selector heading configuration to no avail.

Sitemap:
{"_id":"test","startUrl":["https://www.parkrun.com.au/maitland/results/latestresults/"],"selectors":[{"id":"test","type":"SelectorTable","parentSelectors":["_root"],"selector":"table","multiple":true,"columns":[{"header":"Pos","name":"Pos","extract":true},{"header":"parkrunner","name":"parkrunner","extract":true},{"header":"Time","name":"Time","extract":true},{"header":"AgeCat","name":"AgeCat","extract":true},{"header":"AgeGrade","name":"AgeGrade","extract":true},{"header":"GenderPos","name":"GenderPos","extract":true},{"header":"Club","name":"Club","extract":true},{"header":"Note","name":"Note","extract":true},{"header":"Total Runs","name":"Total Runs","extract":true}],"delay":0,"tableDataRowSelector":"tbody tr","tableHeaderRowSelector":"thead tr"}]}

Error Message:
No error displayed, data output simply contains "null" values rather than information shown in web table.
