The app Stocks shows daily changes in dash, billions and trillipns

I have used the phone SE2 just for a few days. At the beginning the Stocks app behaved correctly. Two days ago the daily changes in the green or red boxes started to show a dash or numerical values in trillions or billions. I noticed that there was a report in this community last year. I followed the steps to remove, restart the phone and reinstall. But the same thing happened. What should I do?
