Straight Barrell darts always fish tail & land facing left.. Help

Struggle to throw any type of straight barrel darts as they always fish tail and land facing the left, or land facing upwards. Really want to like the Littler G1s & others but just can't throw them.

Only darts I can throw are Humphries TX1s or other front weighted bomb style barrels.

Any way I can try fix straight barrel throwing? Picture showing my grip & how darts land attached
