Not sure if this is a new bug (or feature :-)), but LR CC always resets any filter set after exporting an image. In Develop module, I have set a filter to show only "Green" color tagged images. When I export an image (right click on the film strip and export), the Filter is reset - now it shows all images not just the "Green" color tagged ones. I have to constantly filter my images.
Is this a bug? If so, how can I submit a bug?
I am using Lightroom CC 10.1, Camera Raw 13.1 on Windows 10.
Yes if I use the Filter bar in the Library Module, Attribute option, Pick a Color label to show Only those images with that color label and then go into the Develop module and select one then Export it that Filter choice is then reset back to None.
Simple Solution. In the Filter bar after Setting whatever Filter you want to apply Click the LOCK icon on the far right To LOCK that/those filter choices. Then they will not Reset to none. To get out of that you then Un-Lock the Filter bar by clicking that icon again.
You can also Create a New preset with all those, whatever, choice you have selected so you can easily Recall them at any time.
But other than using a Smart Collection in the Collections section of the left hand side panel in the Develop module there is no filter bar in that module. You first have to SET a Filter in the Library module.
That is something you left out of your description, steps, in your first post.
