I know this is an old thread, but in case anyone else is looking for answers...
I imported all 70,000 images straight, just with .xmp files from Lightroom, so essentially, a clean import with no real connection to the LR catalogue itself. I have found that the filters panel will nearly always regenerate when I select a new folder, and of course takes many minutes when selecting all images. Occasionally, after a catalogue database repair (which is needed often with the delicate C1 database unfortunately), the filters panel does not regenerate. However, usually after a bit of meta data and/or keyword manipulation of a few hundred images, everything goes back to normal, with regeneration of the filter panel evident on selecting a folder to display.
Yes, I knew all of this before I purchased C1, but was hoping that updates would eventually solve these issues. There has been some progress, especially on importing with v 11.1, but so many cataloguing functions that were fairly robust in LR are broken in C1.
Some people who use a small number of images, or who do not use all the functionality of the DAM side of things, may not notice all these things, so it is likely you will find replies on these forums where people cannot reproduce such problems. As someone who uses keywords, filtering and advanced searching alot, the limitations created by what appears to be the rather delicate nature of the database and the subsequent time it takes waiting for things to happen, or not happen as the case may be, is taking its toll...
