Sister no longer coming to my wedding

A bit of a long wounded story so I’ll try keep it short. I had four bridesmaids two of which were my sisters. One of my sisters has been trying to rail road everything, taking over the henny trying to organise what she wants and not what myself and everyone else wants. She upset two of the bridesmaids and my mum over it all. She then paid the full amount but said she wasn’t coming cause it’s not her thing, but has still never told me or apologised for upsetting everyone.
I’ve been totally relaxed with dresses, there was a dress and 7 different styles I said to them to pick whichever style they felt most comfortable in as long as they are in the same colour that’s all that matters, they can pick their own shoes and I’ll pay for them again so they can be comfortable on the day. Anything has been a major hassle / drama for her.
Our wedding got rescheduled due to COVID and six weeks later she still hadnt acknowledged it had been rescheduled, let alone offer any support. I eventually asked her if she was still ok being bridesmaid as she was giving me the impression that she had no interest in the wedding. Her response was that she has no interest in my wedding, it’s not her priority so why should she acknowledge it has been rescheduled? She is not jumping through hoops anymore for a self centred selfish queer f**er to remove her from everything she wants nothing to do with the wedding. I calmly tried to reason with her saying we still wanted her to be a bridesmaid but was there an issue or something wrong. My other bridesmaids have continually been saying to me that I am being far to relaxed that I need to let them help more etc so no one can understand why she thinks she has been asked to jumped through hoops. She is now refusing to come to the wedding Altogether and is only going to show face at night to collect her kids ( although has only told family not myself). Should I just forget about the fact that she’s not going to be there with the rest of our family on my big day or should I continue to try and reason with her to get her to come?
