Built in Braille question

Braille on Apple Products

On behalf of a friend who uses an iPhone 8+ running IOS 13.5:
For years she uses the built in Braille keyboard with success, but after upgrading to IOS 13.5 problems occur when she type certain letters. For example:
Typing dots 1 and 3 is suppose to create a letter K, but VoiceOver says it is a letter l> Does anyone experience the same issue?
