Wrong/combinations of home row mods triggering

Hi, I'm trying to add Home Row Mods to my Iris rev 4 and I've run into some issues.

Adding my code changes to add home row mods:

// keymap.c
#define HRM_A       LGUI_T(KC_A)
#define HRM_R       LALT_T(KC_R)
#define HRM_S       LSFT_T(KC_S)
#define HRM_T       LCTL_T(KC_T)
#define HRM_N       RCTL_T(KC_N)
#define HRM_E       RSFT_T(KC_E)
#define HRM_I       LALT_T(KC_I)
#define HRM_O       RGUI_T(KC_O)

...

const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {

  [_COLEMAK_DH] = LAYOUT(
  //┌────────┬────────┬────────┬────────┬────────┬────────┐                          ┌────────┬────────┬────────┬────────┬────────┬────────┐
     KC_ESC,  KC_F1,   KC_F2,   KC_F3,   KC_F4,   KC_F5,                              KC_F6,   KC_F7,   KC_F8,   KC_F9,   KC_F10,  KC_F12,
  //├────────┼────────┼────────┼────────┼────────┼────────┤                          ├────────┼────────┼────────┼────────┼────────┼────────┤
     KC_TAB,  KC_Q,    KC_W,    KC_F,    KC_P,    KC_B,                               KC_J,    KC_L,    KC_U,    KC_Y,    KC_SCLN, KC_QUOT,
  //├────────┼────────┼────────┼────────┼────────┼────────┤                          ├────────┼────────┼────────┼────────┼────────┼────────┤
     KC_LSFT, HRM_A,   HRM_R,   HRM_S,   HRM_T,   KC_G,                               KC_M,    HRM_N,   HRM_E,   HRM_I,   HRM_O,   KC_RSFT,
  //├────────┼────────┼────────┼────────┼────────┼────────┼────────┐        ┌────────┼────────┼────────┼────────┼────────┼────────┼────────┤
     KC_LCTL, KC_Z,    KC_X,    KC_C,    KC_D,    KC_V,    KC_ENT,           RGB_TOG, KC_K,    KC_H,    KC_COMM, KC_DOT,  KC_SLSH, KC_BSPC,
  //└────────┴────────┴────────┴───┬────┴───┬────┴───┬────┴───┬────┘        └───┬────┴───┬────┴───┬────┴───┬────┴────────┴────────┴────────┘
                                    KC_LGUI, LOWER,   KC_ENT,                    KC_SPC,  RAISE,   KC_RALT
                                // └────────┴────────┴────────┘                 └────────┴────────┴────────┘
  ),

...

// no changes were made to my `process_record_user`, I can add it as well if it's necessary

...


// config.h
#define TAPPING_TERM 200 
#define IGNORE_MOD_TAP_INTERRUPT        
#define TAPPING_FORCE_HOLD             

The issue I have is that the wrong mods are being triggered, and for most keys it's even triggering a combination of mods. I have no idea how this can be caused by my simple code changes. See the issue demonstrated in this gif:

Has anyone run into a similar issue? I'd appreciate any help!
