swgoh.gg guilds api out of sync with the website?

As the title suggests - the data returned by the https://swgoh.gg/api/guilds/<guild#>/units/ is different from what the website shows? For example some guild members are showing as part of our guild but the api does not return their units.

I asked the members to force update their profile, but after doing that and waiting for couple of hours - still the api does not return those member's units.

Any ideas?
