"Paste and Match Style" changed to "Paste and Preserve Style". Why?

[jsx97]

1. Open Keynote, click Edit in the menu bar and see the sixth element is "Paste and Match Style".

2. Install Karabiner Elements and add the following karabiner.json:

   {
       "global": {
           "check_for_updates_on_startup": true,
           "show_in_menu_bar": true,
           "show_profile_name_in_menu_bar": false
       },
       "profiles": [
           {
               "complex_modifications": {
                   "rules": [
                       {
                           "manipulators": [
                               {
                                   "description": "Change caps_lock to control+option+shift+command.",
                                   "from": {
                                       "key_code": "caps_lock",
                                       "modifiers": {
                                           "optional": [
                                               "any"
                                           ]
                                       }
                                   },
                                   "to": [
                                       {
                                           "key_code": "left_shift",
                                           "modifiers": [
                                               "left_control",
                                               "left_option",
                                               "left_command",
                                           ]
                                       }
                                   ],
                                   "to_if_alone": [
                                       {
                                           "key_code": "escape"
                                       }
                                   ],
                                   "type": "basic"
                               }
                           ]
                       }
                   ]
               }
           }
       ]
   }
   

3. Open System Settings, click Keyboard, Keyboard Shortcuts, App Shortcuts.

4. Set Menu title to Paste and Match Style and the Keyboard Shortcut to Caps Lock-V (that is, Control-Option-Shift-Command-V).

5. Open Keynote, click Edit in the menu bar and see the sixth element is now called "Paste and Preserve Style".

Why does its name changed? And why, despite Caps Lock-V works fine to paste and text and match/preserve style, the Paste and Preserve Style item is always greyed out in the menu?
