I checked today, and that's what happened. I think it's been like that for me. Is it not like that for you, @XTRA-Larsiano?
I just checked again now, and it's still the same.
In fact, if I have any of the 14 missing melee weapons equipped, then the loadout in the Customization menu will change my knife to the default combat knife.
Yes its the same for me as all these items are missing from the menu, I've never noticed before. But I've stopped to use this and the website selection a long time ago since its hard to use and doesn't store it correctly. In game i've only had this problem once quite some time ago but it disappeared after a reboot. In game I've been using the Ararebo since i got this and a star for all the other melee weapons.
Are you able to see the weapons online dough?
If by online you mean while playing or in the deploy screen, then yes, I do see it there.
Also, as a correction, the Customization will default to the combat knife if you have any of the 14 missing melee weapons equipped on your soldier. However, it reverts back to the original equipped melee weapon unless you manually change it in the Customization screen. So, even if it shows the combat knife as being equipped, it doesn't actually change your loadout unless you physically change the melee weapon.
