Darla in Season 1 of Buffy?

[Buffytheslayer]

Im new to the Joss Whedon universe, and started watching buffy on netflix a few months ago, then continued on to Angel. Watched both series, and I am starting to watch buffy again. I was re-watching season 1 of buffy and did anyone else notice that Darla is in it, but was supposed to be dusted already by Angel? It showed during an episode of Angel, (not sure what season or episode) anyways, it showed his past, and what he was like after meeting up with Darla right after being cursed with getting his soul back from the gypsies, and Darla wanted nothing to do with him, and if im not mistaken they faught, and I swear that Angel dusted Darla. The timeline doesnt fit cause didnt Angel get his soul in the 1800's? I could very well be mistaken. But I thought I saw Darla get dusted WAY before she could have been in Season 1 of Buffy. Just thought it was funny, and a mistake on the writters part if I was right. But basically, I was wondering if anybody else noticed that, or if Im wrong.
Sorry about the long ramble
