Pulling data from google analytics split by week (with dates) results in a table that is sorted by alphabetical, not chronological order: https://www.dropbox.com/s/dwu732c4nlosatv/Screenshot%202018-03-05%2020.06.17.png?dl=0
Trying to set the "sort order" by week ascending or descending results in this error: https://www.dropbox.com/s/8aoq52tm0kzzdng/Screenshot%202018-03-05%2020.43.23.png?dl=0
Thanks for reporting this, there seems to be a bug in that split by dimensions.
Our developers will have a look, and contact you once it's solved.
Thank you! Will be looking out for updates.
