renaming website page urls

I’m definitely a novice with WordPress
Our website is https://njpada.org. It has a number of pages. The url for each page shows the database name. how can I eliminate that.
Example: https://njpada.org/wordpress_1999214231/1642287026784/meetings/
I just want it to show https://njpada.org/meetings.

If I type https://njpada.org/meetings in the url bar, I would like to connect directly to the meetings page. Instead, it goes to the home page.
Could someone show me how to correct this? Then I could apply it to each pae.

The page I need help with: [log in to see the link]
