InDesign Recent Items to Display Greyed Out
Windows 10 64-bit Pro
InDesign CC (updated)
Recently, for all users on our subscription, we are not able to see recent items in InDesign.
Preferences > File Handling > Saving InDesign Files > Number of Recent Items to Display: 0 is greyed out, so we cannot change this number.

No settings that we are aware of have been modified, and this just started happening within the last few days. Any information on how we can get that box ungreyed is appreciated!
