Network Map issue with NIS 19.6.1.8

After the NIS 19.6.1.8 update was installed the Network Map started to behave strangely.  The map will no longer remember a device name or category name that I enter manually.  The strange thing is that it doesn’t forget the names immediately.  I can take 30 minutes.  This issue only seems to affect new devices that were not on the map prior to the update. I have two computers with NIS12 and this is happening on both of them.
