Hello @Gabriel Lundgren ,
Please check the sample attached.
There is an issue with component, if we have a text column like company name/comment and we enter data something like date '2021-12-20' or 2021-12-92 and save all,
next time, While rendering , it considers that column as date column even if it is text column at backend , when we click on edit All, and if we try to change the data of any field it wont allow you, as it doesn't give you changed lines as it doesn't find that date column present..
You can try out in the attached sample. Can you please look into the issue and Let us know the ETA for this as this is pretty critical issue for us.
