We recently upgraded to SW 2019. My colleague noticed that you can no longer cut and paste custom properties from one part to another (or rather, you can paste them in and click OK, but the next time you open custom properties the properties you pasted in are no longer there)

We tried it with 2019 parts as well as 2018 parts.

We also noticed a new column titled "F" when we paste custom properties into the part. All the values in the F column are 0.

Can anyone duplicate this problem? Anyone found a way to fix it?
