Unable to name a download of images

I have a rather peculiar problem with Lightroom, which is somewhat difficult to describe.  First, I have the current version of Lightroom with the latest updates installed (Lightroom_Catalog-v13.lrcat). Here is the problem: I was trying to download some photos, and when I was trying to enter a name for the download, I was unable to finish entering the name because when I typed the remainder of the name nothing appeared. I was able to use the part of the name that I had typed as the name of the download, which made it possible to download the images. The part of the name that I had typed could not be deleted or completed. Since I could not delete it, I used it for a subsequent download. I tried to use the “Rename” function to change the partial name to the proper name for both of these downloads; however, this did not work. So, I was left with a partial name in the box for naming downloads which I couldn’t delete. While trying a variety of things to solve this problem, I somehow managed to delete the partial name; however, now I can’t enter anything in the box, so I can’t download anything.

Another peculiar thing happened at the same time that I lost the ability to enter anything in the naming box: I lost the ability to designate an image to be deleted by hitting the X key on the keyboard; however, I can still delete an image by using the cursor to indicate that it should be deleted.

I haven’t the slightest idea what I can do to solve this problem. Any help would be appreciated.
