Space key binding

I got a problem with my space buttons binding :

• In calendar mode Doesn’t trigger the list mode but enter does
• In list mode Doesn’t trigger the view mode but enter does
• In view mode Goes back to the list mode but enter goes to edit mode

Here is my complete keybindings section

[keybindings]
delete = d 
down = down, s
export = e 
external_edit = meta E
left = left, t, backspace
mark = v 
new = c 
other = o 
quit = q, Q
right = right, n
save = meta enter
search = / 
today = g 
up = up, r
view = space, enter

I used ikhal with the -v flag but I got no message on my ineffective space press.

Thanks for your work !
