App doesn't show hints for writing keycodes properly

[seflm]

Some users are getting hints when writing the keycodes into the "any" key and the encoders:

But for some other users (me) the hints are not provided by the app for some reason:

I've got the following JSON and the only hints I am getting are from the qmk_lighting, VIA is not providing hints for basic keycodes (e.g. KC_A), but for others, it does. I haven't managed to find out any reason why it would behave this way. The docs do not cover the hints whatsoever.
