Describe the bug
When importing a custom keymap JSON file in VIA for the Epomaker EK21, it says “layout updated” and shows the updated layout, but actually it didn’t work and the keyboard wasn’t updated like expected.

To Reproduce
Steps to reproduce the behavior:

1. Buy an Epomaker EK21.
2. Remap one key.
3. Export custom keymap JSON file.
4. Remap same key to something else.
5. Import previously-exported keymap JSON file.
6. See the layout in the UI was updated, but the keyboard wasn’t.

Expected behavior
VIA should probably not “lie” and say if the layout was properly updated in the keyboard or not.
