Will finally make the migration from iPhoto to Photos with macOS Catalina. Each picture in iPhoto is has a number followed by text on the Title. MacBook Pro is my main computer. Installed Catalina on my 'guinea pig MacBook' and notice that Photos displays my numerically sequenced pictures--1-2-3-4-5--as 1-10-100-11-12. How can the pictures be sorted by the number that precedes the Title? Thanks.
