message at startup: LocalizedDefaults.plist

[brotherbeary]

When I start up my MacbookPro (10.12.6) I get a popup that reads:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>AB21vCardEncoding</key>
<string>MACINTOSH</string>
<key>ABNameDisplay</key>
<integer>0</integer>
<key>ABNameSorting</key>
<integer>1</integer>
<key>ABNameViewPhotoInsetLeading</key>
<integer>105</integer>
<key>ABShortNameStyle</key>
<integer>4</integer>
<key>ABTemplateNameViewPhotoInsetLeading</key>
<integer>105</integer>
</dict>
</plist>

What does this means and what can I do about it?

Can you take a screenshot of it and post here?
