"Apollodorus of Athens"

It seems our Apollodorus "the Epicurean" and the more famous Apollodorus "of Athens" are now considered two different people, but I need help figuring out why.

They have the same dates:
Apollodorus "of Athens" first came to Athens in 146 BC (in his early thirties) -- and Apollodorus "the Epicurean" died around 100 BC (as an old man).

Apollodorus "of Athens" was associated with Epicureans:
He was originally educated by the Stoic Scholarch Diogenes of Babylon -- but this Diogenes, as we know, was on friendly terms with Philōnídēs of Laodíkeia. (This puts our Philōnídēs, who did visit Athens while representing the Seleucids, in the same friend group as Apollodorus "of Athens")

They both wrote the same book:
Diogénēs Laë́rtios says "Apollodorus [the Epicurean] in his Chronology tells us that [Epíkouros] was a student of Nausiphánēs and Praxiphanes" -- but one of the main works of Apollodorus "of Athens" was his "Chronology"

APOLLODORUS [the Epicurean]
APOLLODORUS [of Athens]

Thank you for helping with this. We know Diogenes Laertius references as his source "Apollodorus of Athens" (7.181) and "Apollodorus the Epicurean" (10.13). This itself might be the source of the scholastic tradition of them being two different men.

Given my arguments above, I do not think two different epithets certainty means two different men. Epithets in Diogenes Laertius are not consistent or systematic.

And at 7.181, it is "Apollodorus of Athens" defending Epicurus, quite like an "Apollodorus the Epicurean" would be expected to do!

• "Apollodorus of Athens, in his "Collection of Doctrines" wanting to show that the works of Epicurus (written by his own efforts and not copied) were innumerably more numerous than the books of Chrysippus, said in these very words: 'indeed if someone were to remove from Chrysippus' books all that was cited from elsewhere – his papyrus would be left empty!'"

I may be overlooking something, but I am not finding him.
