Scattered messages in WhatsApp group chat

Hello,

I recently restored my WhatsApp messages to a new phone. They’re all there until the date the backup was made. However, new messages in specific group chats are appearing scattered through the chat history. For example, a message with the time stamp “today” appears in between messages with a time stamp from more than a year ago and never one after the other. Is there a way to fix this? To make whatsapp do a double take, if you will, at the dates?
