I have zero experience with Jaxx, so I don't know how the wallet functions. But I have heard many negative comments about it to be honest. I assume you have checked the transaction on a blockchain explorer and it's confirmed to have been received in the correct address.
Is there a way to delete your Bitcoin wallet safely and re-add it?
Does Jaxx have a resync feature or a way to delete the cache to fix what the UI is displaying?

But the best option would be to abandon it entirely, create a new Bitcoin wallet with a more reliable software, and transfer all your Bitcoin to it.
