Thanks a lot for posting this article
When one member here posted what the filmmaker Anant Mahadavan wrote on instagram at the time when he did so, I researched for his movie and also posted about what I found out. Then, lately, one member wrote about the short movie.
There are now two possibilities:
1) producers and directress only related on what the writer Biplab Goswami gave them as an "original" story and had been unaware of the short film and Mahadavan's movie or
2) they just decided to ignore that the story wasn't "original" and made everything their own.
Interestingly, now, on Wikipedia, a change had been made (bold):
"Original Story:Biplab Goswami[1]. The film is an adaptation of an Arabic short film Burqa City.
Screenplay and Dialogues:Sneha DesaiAdditional Dialogues:Divyanidhi Sharma
Based on"Two Brides"by Biplab Goswami"
Btw, when Kiran had been asked about the Mahadavan movie when it came on Instagram, she claimed to not have known about it, but obviously 'forgot' to mention Fabrice Bracq's short film...
Edit: I think, one also shouldn't neglect Rituparno Gosh's 2011 movie Noukadubi and - like the member @simplyrdb mentioned - the 1906 novel written by Rabindranath Tagore (whose Noukadubi was filmed already in 1947)...
