We're really sorry for all the hassle. Could you please lets us know the exact version of Lightroom you are using now? Also, please try and reset the Lightroom preferences back to defaults.
To know more about resetting Lightroom preferences, please refer: How to set Lightroom Classic CC preferences
Let us know if that helps.
Thanks for the suggestion. The version is 2015.14
I will try the preferences reset.
No change after the reset.
Is there any specific reason for using CC 2015.14 version? Please update Lightroom to Classic CC(7.5) version and check if that helps.
Using Windows 10, on subscription, and wanting desktop based not cloud I thought the version I am using is the most up to date.
Simon, you're yet another victim of Adobe's confusing branding. Lightroom Classic CC is the next major version of desktop Lightroom following LR CC 2015 / 6. See here for a more enlightening discussion of the various flavors of Lightroom: https://www.lightroomqueen.com/the-future-of-lightroom/ . (It's indicative that customers need a third party to clearly explain Adobe's branding.)
