In the Schema Browser | Data tab, if you type over an existing record to amend it and then click several times in other columns/cells, the value you typed changes back to the original entry saved in the database. The amended data is reverting back to the original saved record.
It is especially prevalent if there is a filter on the table, but this is not always required.
It also happens on any table in the database.
Steps to Replicate:
1. Go to data grid
2. Add a filter to filter one row
3. Change data in one column, click in the next columns a few times and the data changes back to the original record.
