Missing icons on Qt 5.12

Question

Until now I had used mapbox://styles/mapbox/navigation-preview-night-v2 style, which was working fine. But when I changed my style to "Navigation"(which is default template from Mapbox Studio), I got following warnings:

[ WARNING ]  "{QSGRenderThread}[ParseStyle]: [3]: Expected arguments of type (number, number) | (string, string), but found (value, number) instead."
[ WARNING ]  "{QSGRenderThread}[ParseStyle]: [3]: Expected arguments of type (number, number) | (string, string), but found (value, number) instead."

And my map does not have half of icons on it.

To make it work had to replace 

["get", "filterrank"]
["get", "sizerank"]
["get", "symbolrank"]
["get", "len"]
["get", "reflen"]
["get", "layer"]

in filters with

["to-number", ["get", "filterrank"]]
etc...
