After making some changes to a Data Table, attempting to PIE fails and returns this error message: Cannot Play In Editor When Performing Edit MemberVar_1 operation. This occurs after closing and saving the new Data Table. This also only seems to occur when using the slider to enter a value. Entering the value with the keyboard did not cause the error warning to appear.

Found in 4.10.1 binary. Reproduced in 4.9.2 and 4.11 Preview 1.

Steps to Reproduce

1. Open the editor
2. Create a new struct and add an int variable
3. Create a data table using that struct
4. Add a new row
5. Use the slider to edit the int variable on that row
6. Save and Close the data table
7. PIE

Result: Warning appears and PIE does not begin

Expected: PIE would begin without issue
