After importing a run of FCS files, we noticed that the keyword we use to hold the specimen id was wrong in one of the files. I deleted the run (essentially, did an "un-import"), updated the file to have the correct value for that keyword, then re-imported the run/folder. After the re-import, the keyword value for that file was still the old value, as shown in the FCSFiles view, and as shown in the details view of the specific FCSFile record. I downloaded the file via the "Files" web part, and checked the value of the keyword in the file: the value was the new value. Saw this on two different files in two different runs. I tried this several times, and saw the same behavior every time for these two files/runs. I had to manually edit the keyword value on the FCSFile details page to correct them.

I have done similar corrections in the past (delete run, change keyword values, re-import run), and never saw this behavior.

Why would the import not pick up the changed keyword value?
