Does this mean they are flirting with me?

I’m a nice guy and I’m nice and talkative to all women, even though I have a girlfriend. At work, I think some women take it the wrong way. I tend to offer to buy them snacks at our vending machines at work, I have even given a few a ride home. I’m just an overall playful and friendly guy but I think it gets taken out of context. Like today for example, a group of my women co workers walked by and they all were like “Heyyy (my name)” while not even acknowledging one of my other woman co workers who was right next to me. This is why I believe they may be flirting and my niceness could be sending the wrong message.
