3 transactions made and showing on summary , but only one transaction showing in balance


Over the past couple of months I’ve purchased ADA and had no issue with what was on my balance. …a couple of days ago i couldn’t connect to my wallet so decided to uninstall and reinstall.
Upon reinstalling, the previous two transactions I made don’t show on the balance ,but show on the summary .I then decided to send recently purchased ADA thinking it may sync ,but only the recent transaction out of the three are showing in my balance …help !!
