Only first import works with Lightroom
I am running Lightroom CC 8.1 on a MacBook with OS Mojave 10.14.2. I can import files into lightroom fine when I first start lightroom but if I try to import again the import screen gets locked behind the sidebars and I can't control what to import. I can re-boot Lightroom and import, but that's a pain. Anyone have an answer or similar problem?
