Suddenly Lightroom 15.9 has developed several anomalies.
This just starrted happening after I had LR just lagged badly. Rebooted computer and this started happening.
Windows 10. LR uptodate.
1 is because you have not selected Add at the top. It is set to Copy. This is something you need to check on every import.
When Add is selected the Destination section isn't visible and can't be activated.
2 is because of the same reason. Not having Add selected. With Add select the Rename section is visible and can't be activated. Again something you need to check and select on every import.
