Can't change letter behaviour when setting default layout

[argenkiwi]

Using v4.2.3 and the following configuration:

include layouts/colemak

[ids]

*

[default:layout]

[global]

default_layout = colemak

[main]
a = overloadt(control, a, 256)
s = overloadt(shift, s, 256)
d = overloadt(meta, d, 256)
f = overloadt(alt, f, 256)
j = overloadt(alt, j, 256)
k = overloadt(meta, k, 256)
l = overloadt(shift, l, 256)
; = overloadt(control, ;, 256)
space = overloadt(space, space, 256)

[space]

a = overloadt(control, a, 256)
s = overloadt(shift, s, 256)
d = overloadt(meta, d, 256)
f = overloadt(alt, f, 256)
j = overloadt(alt, j, 256)
k = overloadt(meta, k, 256)
l = overloadt(shift, l, 256)
; = overloadt(control, ;, 256)

For example: holding s and tapping h produces h instead of H. While holding the space bar, the result is the expected. If default_layout is not specified, the result also is the expected.
