Multiple filters and to-number fails

[chau-intl]

I am trying to create a filter which consists of an equal and a larger-than part:

A = 'my-value' AND number(B)> 2

This I write as:

 "filter": [
    "all",
    ["==", "A", "my-value"],
    [">", ["to-number", ["get", "B"]],2]
  ]

but it doesn't work giving me the error message: string expected, array found on the line with the to-number.

If I remove the equal filter, the greater-than filter works just fine:

 "filter": [
    "all",
    [">", ["to-number", ["get", "B"]],2]
  ]

What am I doing wrong?

I am using Maputnik 1.7.0.

I have discovered, that if I change rewrite my original filter from:

 "filter": [
    "all",
    ["==", "A", "my-value"],
    [">", ["to-number", ["get", "B"]], 2]
  ]

to:

 "filter": [
    "all",
    ["==", ["to-string", ["get", "A"]], "my-value"],
    ["<", ["to-number", ["get", "B"]], 2]
  ]

it seems to work, though the UI isn't very helpful using these types of filters.
