Norton Download Manager - two files named FSDUI.exe and FSDUI_NIS.exe

At various times I look at Norton Internet Security History to check the different categories and see what has been submitted via Norton Community Watch.  A few days ago I had seen that two files were submitted at least once:

FSDUI.exe
FSDUI_NIS.exe

They are known as Norton Download Manager v5.0.1.83. Their Digital Signatures are valid. The location of these files show that they are for NIS v21.0.1.3 - whereas I am on latest release of 21.7.0.1.  They seem to be new files that were created on 6/5/15 and there are two sets of locations for them - C:\ProgramData\Norton and C:\Users\All Users\Norton.   Also, even though they were 'submitted' succesfully at least once, they are still continuing to be submitted for past 3 days - since the evening of 6/9/15.  The status is always 'pending'. Attached are PDF's (screen grabs) of the files I am talking about. Has anyone else noticed these two files present in their Security History -> Norton Community Watch logs? Am seeking to see if this is normal or if something else altogether. Other than that, I have no problems at all at present with NIS.  Comments and feedback are most welcome.  Thank you.
