Hello! I have a table that ended with "ghost" default sort items and can't be deleted in any way. How could I get help with this? It's breaking my application. 
Steps to reproduce:
What happens:
The table has now default sort references to un-existing columns and these can't be removed in any way.
Hi @hector Thanks for reaching out about this bug.
We have reported it to our team. I don't have an eta, but I can reach out here if they ship a fix.
In the meantime, the two workarounds I can find are:
1). Export the app json and manually clear the defaultSort array to []. Import the editing json back into your app
2). Not ideal, but another option is to manually re-create the table from scratch
Hope one of those workarounds helps for the time being! 
Thanks for the alternative solutions. I ended up recreating the table but next time I’ll try the JSON export/import hack.
