I've got some troubleshooting steps you can perform to isolate the issue so you can continue working with your bank feeds.
To clarify, is the Banking page unresponsive or not loading new transactions? If the page takes too long or fails to load, it's possible that you have too much accumulated historical data.

Not to worry, clearing them will do the trick.
