Problem with the custom analyzer

We have installed elastic search for one of our products using AWS Elastic search service, the problem is that we have defined an analyzer with typo in the type of the analyzer "custome" instead of "custom", the thing is AWS ES accepted this configuration during all the testing phases and when installed on production.
after the release we wanted install a new service using the same configuration but it started throwing the following error message "Unknown analyzer type [custome]".
I hit on production to see how it is configured, and it shows "custome" is accepted for the installed analyzer index, and now we are lost on what should be done to fix this on production, and why it did accept the faulty configurations in the first place ??????
