Mini poodle not getting along with Frenchies.

I have a 3 year old mini poodle who is a bit of a social butterfly and loves almost all dogs. I take her to a dog park for small dogs where she plays with all the other dogs and never has had any issues. Then there was a frenchie who kept trying to play but would sort of stampede her and she hated it ( even though she wrestles and jumps around with other pups). I think she got really scared and if it would approach she would growl, at it to leave her alone, but it did not listen so I just take her away. She loves playing with all the other dogs so much so I still bring her but she keeps a wide berth if that dog is there. I thought it was just that dog but today there was another one there and it full on jumped on her pretty aggressively and someone grabbed him off her. They were both fine but I’m wondering what’s going on. I’m wondering if I can train her to not get close to them ( obviously I can remover her too) but she loves the play time so I don’t want to stop completely. I also feel like these two were not bad dogs but maybe super different play or communication styles. Any ideas to stop her getting reactive to them in general going forward?
