RALT() not working

Hello,

I’ve been banging my head for a few ours and I cannot seem to find the right hint in the documentation, the forum, or anywhere else. The RALT() (macro?) doesn’t seem to work. Here is a keymap that is supposed to function as a special characters layer (derived from Neo/Bone layer 3):

[PMB_L3] = KEYMAP_STACKED

  (___, ___,             ___,               ___,                 ___,                      ___,                ___,

   ___, M(MACRO_ELLIPSES), LSHIFT(Key_Slash), RALT(Key_8),         RALT(Key_9),              Key_Backtick,       ___,

   ___, RALT(Key_Minus),   LSHIFT(Key_7),     RALT(Key_7),         RALT(Key_0),              LSHIFT(Key_RightBracket),

   ___, Key_NonUsPound,    LSHIFT(Key_4),     RALT(Key_Backslash), RALT(Key_Backslash),      LSHIFT(Key_Equals), ___,

   ___, ___, ___, ___,

   ___,




   ___, ___,               ___,           ___,                   ___,                    ___,                   ___,

   ___, LSHIFT(Key_1),     Key_Backslash, LSHIFT(Key_Backslash), LSHIFT(Key_0),          LSHIFT(Key_6),         ___,

LSHIFT(Key_Minus), LSHIFT(Key_8), LSHIFT(Key_9),         Key_Slash,              LSHIFT(Key_Semicolon), RALT(Key_Q),

   ___, Key_RightBracket,  LSHIFT(Key_5), LSHIFT(Key_2),         LSHIFT(Key_NonUsPound), Key_Semicolon,         ___,

   ___, ___, ___, ___,

   ___),

According to What can go on your keymap — Kaleidoscope documentation it should work out of the box, but none of the keys defined using RALT doesn’t do anything while LSHIFT and LCTRL work as supposed to. What am I missing?

Thanks & best regards,
