When searching on the mutations page, the fields that are being searched include invisible data. In this example, I have made all columns visible and I search for "55". The only fields with "55" are the start/end position, but if this field was being searched then all the EGFR mutations should be found, and only 2 of them are. Thanks to @ersinciftci , we figured out that the "mutationId" field for both of these mutations includes "55" so it appears that the search feature is searching the invisible "mutationID" field.

@onursumer maybe this can be fixed in the new code.
This is by default fixed within the new code, we don't have any hidden filters for the new mutation table. I don't think it is worth fixing the legacy code.
