Self correction needed
It can be a bit frustrating to try to remember which version of an answer is correct to complete a set. For example, when we type ... didn't ... and their answer has ... don't. I know we can usually report ... My answer should be accepted ... but we should be able to self-determined when we has a correct version of an answer so that we can progress faster through sets. On occasions we might be incorrect, but over time this will sort itself out.
I think this happened with another language too. This become more problematic since Indonesian is a tense-less language. i think the solution is the contributors keep inputting all the possible accepted answers, but it takes times.
So for now just keep reporting and hope the contributors keep "contributing"
