Sender Whitelist entries disappear when switching tabs in User Portal

This is the correct forum, as User Portal issues come under the Management section, so I've merged the double posting.  How many entries do you have in a list?  Is it a large number?  I've not seen this specific issue before, but have seen similar, which was caused by a bad entry with illegal characters..  

Might also be related to a known issue:

ID33858 9.209 Userportal - adding multiple addresses to whitelist/blacklist does not work
------------------------------------------------------------------------
Description:  It is not possible to add multiple entries to the sender
              whitelist/blacklist in User Portal (SMTP) in one step.
              
              When a user accesses the User Portal, adds multiple
              entries to the sender whitelist/blacklist,
              then leaves this page, only the first entered entry is
              saved. Others entered during the same
              session are not saved and have to be re-entered. 
              
              Workaround:
              Add one entry per session, browse to another tab, then
              come back to the whitelis/blackist tab,
              enter another address and safe it again. Repeat this steps
              if needed.
              
              Steps to reproduce:
              1. Login to User Portal
              2. Select Whitelist or Blacklist
              3. Add multiple entries and click green check box to save
              each entry
              4. Change to a different tab (doesn't matter which)
              5. Browse back to whitelist/blacklist tab
              6. Issue occurs (only the first entered address appears,
              the rest are lost)

Hi, Scott,

Thanks for merging my double entry!

The article you referenced seems related, but it doesn't quite cover my issue, which is that I always seem to lose at least one whitelist entry, regardless of whether I add, remove or edit even one entry.  In other words, if I want to add just one whitelist entry, I have to do what the article suggests and add at least two entries, while switching tabs in between entries: the one that I lost, plus the new one.  I now keep an OCR'd screenshot of my whitelist in OneNote, and I always compare it to the whitelist tab, before I make any edits.

At the moment, I only have 19 whitelist entries - hardly a large amount.  I don't use any strange characters, but I do have one *@*.community.sophos.com entry and one *@*.dealsaver.com entry; I don't know if those are considered "legal" entries, due to the double asterisks.  I'd love to just include *@*.sophos.com, but I don't think that would capture sub-domains, would it?  I think it's funny that UTM flags as spam and quarantines email from noreply@mail.community.sophos.com.

Regards,
Edgar
