Basically खुला -> खुल्ला ?

Google translate things they both mean "open" and I think I see the latter in https://ne.wikipedia.org/wiki/%E0%A4%96%E0%A5%81%E0%A4%B2%E0%A5%8D%E0%A4%B2%E0%A4%BE_%E0%A4%B6%E0%A5%8D%E0%A4%B0%E0%A5%8B%E0%A4%A4

Oh, and you're the original translator as well. Thanks @nikeshbalami !

Thanks for the merge @mlinksva, I was also thinking same, खुला = खुल्ला but currently while doing translation of Open Data Handbook, linguist of Nepal suggested me खुला = Hindi word and खुल्ला = Nepali, so making correction :)
