Banana 9 under Mac OS 10.15 Catalina - adjustment of date

Problem

After updating to Mac OS 10.15 Catalina, the Banana 9 program displays dates as follows, everywhere a date is being used:
6/10/y ; 7/10/y ; 8/10/y - showing a "y" instead of the short indication for the year, such as "19" (2019), "20" (2020).

System

Mac OS 10.15 Catalina

Solution

• Click on the Apple symbol in the upper left corner of the screen
• System Preferences —> Language & Region —> Advanced -> Dates;
• In the "Short" field, change the setting for the year and reopen the Banana program.
