iOS 16 Messages

when I send a message and edit it, the other persons phone shows “Edited to” and whatever the message was in a new blue text bubble. But when they send a message to me and edit, it just shows where they’ve edited the message and the original one is no longer there. We both have iOS 16 I’m just wondering why is this happening? Any ideas? The screen shot is from their phone showing what my messages look like to them
