Ground wire not long enough in 4-prong dryer cord?
It appears to me you didn't buy the Whirlpool brand cord, WP has ring terminals not forks. It is quite possible the maker of your cord didn't expose enough conductor to spread the connections for your dryer. Your options would be to get a WP cord or cut the black jacket back another inch or two and loop line conductors a little below the terminals.
Do leave the bonding strap in place where you have it and as the instructions show. Many people don't realize that on Whirlpool dryers the other end of that 4&quot; long green wire is a stake-on landed right back on top of the neutral terminal, and as connected for 4 wire connections it is just a pointless loop. Here is a picture of that wire https://amzn.to/2IJBUKl .  It's just a place holder when wired for a 4 wire, but the part is present and moved to the ground screw if your only option is a 3 wire connection.
