I have a large collection of data with one text property containing empty cells for most items. I changed the cell of one item to a string of text, but have since needed to revert back to the empty value. However my code is now reading this cell as "", not null. Now, I could amend my code so that it also behaves in the desired way for "" values as well as null values, but to me it seems odd that I can't revert an item's value back to null in the live database accessed via the dashboard.
Edit: I should also point out that filtering the live collection by "cell is not empty" still returns the item where the cell is empty, i.e. "".
