inaccurate box office

Hi there, the worldwide gross is inaccurate for Capture Kill Release): https://www.imdb.com/title/tt5363736/

The figure shown in "Gross (World)" was submitted by one (poorly organized and run) festival that didn't even confirm they accepted the film until afterwards. The film played many more (and far more successful) festivals yet this is the number that remains on there which has had some publications picking it up as "biggest bomb of the year" 

Can I get some help removing this figure? I have tried to edit the box office in IMDb but the option to remove it isn't there.

Thank you very much!

Thank you!
