Thanks, Leo, but that does not correspond to my problem.

In my case I can verify that although the Calculations list shows a correct
prediction, it does not appear in the Sky plot, nor in the list by 'Find
satellite in sky' (and that list very clearly lacks lots of already
predicted sats, and if I KNOW which object I need to identify (!), it does
show up if I add it to the user list.

But it is extremely impractical to add ALL satellites to the user list,
since I cannot keep a backup of the old contents, useful for classified
predictions, and time consuming to use search and add several matches , and
then remove them.
