Help on error messages

Yesterday I upgraded from Jarvis 16.0 to release 16.1 and have begun to see error messages that I wish to resolve
I am running Kodi Jarvis 16.1 under Windows 10 on Dell AIO PC.

first is an ERROR message about Window Translator
2nd one is a warning notice message about JSONRPC

I have not been able to find any leads on how to resolve these messages. I did a FRESHSTART to take back to Kodi defaults in and attempt to eliminate the presence of any ADDONS
no luck and errors continue to be logged in Kodi Log file.

I enabled PVR Simple Client upon initiation…. but took care so no other applications activated.. other than to install the provided Log File Browser/Viewer ADDON. but took no actions to complete and Configuration panes
so that environment is purely Kodi and without any 3rd party AddOns

1st ERROR message seen in log is

Window Translator: can’t find window filestackingdialog

followed by next ERROR message

previous line repeats 1 times.

then

2nd error message is JSONRPC

JSONRPC error message is a WARNING message

JSONRPC could not parse type “Settings.Detail.SettingsList”

this message immediately preceeds the NOTICE message PVRManager starting up

can you offer insight into the possible cause of these errors.

once again .. this is upon start up after performing the Kodi Provided FRESHSTART Addon and before any 3rd party Addons have been installed into the environment

Thank you.
