I have noticed that Yahoo Finance has not updated the ETF yield data for specific stock tickers. For example, you have the yield for Invesco "PGX" at 4.87% and it has been like this for months. The actual stock yield is around 5.23% as this adjusts each time the price goes down. This could be misleading to new investors.
