Lemon Traveller spotted outside its range - Eastern Cape South Africa (1 Viewer)

Hello! I am currently doing an internship with Oceans Research on Schotia Private Game Reserve in the Eastern Cape of South Africa. While doing some butterfly transects, we came across this butterfly that looks to be identical to the Lemon Traveller/Lemon Tip butterfly, however both sources we have checked only note this butterfly to be at the Northern edges of South Africa. I was hoping someone could confirm that this is that butterfly and if anyone had any other information of spotting these in the Eastern Cape. Thanks!

the photo didnt upload at first- here it is

I'm not convinced it isn't Common Orange Tip based on the extent of orange at the forewing tip, blackish smudges near the body on the forewing and very feint black marks suggestive of worn, dark chevrons at the trailing edge of the hind wing.

It's very worn but the remnant features I noted, suggest the more likely Common Orange Tip to me?

It's also noted that the female Lemon Traveller (which this would be) is even more sedentary than the male which would make it even less likely?
