Messages disappearing after changing date

I have an iPhone SE and I have been experiencing problems with my messages. Recently I changed the date on my phone. After I put it back to the normal date, my messages have been acting up. Whenever I send a message, it goes through and can be seen by the other person but disappears on my screen. People send me messages and I get the number stamp on the app but when I open it I see no new messages. Later people have asked why I haven’t replied which proves they have sent me messages. (If that makes sense) My question is if anyone knows how to fix this problem?
