Support has always told me to open a case up when we need something unmasked as it might be a change in the configuration to get that data. With that being said, Id have to recommend that route.
As far as I've observed, it looks like masking if it is a number, rather than ignoring the number because the behavior is the same even though api version exists only v1. I assume it's more of a reflexive algorithm than a smart one.
It should also be possible to display the following ;
Clund Foundry application --- api-jobinfo-v1, api-jobinfo-v2
