Question About Proficiency on Weapons

[BiosTheo]

So I had a quick question about the wording in proficiency with the Shadow Assassin class (3rd party) but this does crop up elsewhere this is just a pertinent example. So:

Weapon and Armor Proficiency: A shadow assassin is proficient in all simple weapons, all light weapons, as well as bolas, net, repeating crossbow (light only), shuriken, spiked chain, and whip. The shadow assassin is proficient with light armor and small shields, but not heavy shields or tower shields.

So I've bolded the pertinent part for discussion. Does this mean all light weapons (indicating all light martial as well as exotic) or all light martial weapons?

[Imbicatus]

As written, it means all light weapons, regardless of if they are martial or exotic.

They are also proficient in "small shields" which don't exist. There are light shields and bucklers, that could be either one.

This seems to be a poorly written proficiency section.
