Can’t remove recipients after added

Hello,

I’m testing out this on a local WordPress.
I have 2 issues.

1. Can’t remove recipients.
After adding recipients to the conditional email, I can’t remove them by removing the user and clicking the [Update] button.

Is this a bug?

2. Toggle button is crooked.
Also, the on/off button for “Send only to recipients” seems to be crooked.
Changing CSS to the following fixed the issue:

.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch input,
.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch label {
    top: 15px;
    left: 10px;
}
.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch input:before,
.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch input:after {
    top: 0px;
    left: 0px;
}
.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch label:before,
.cmb2-id--gamipress-conditional-emails-recipients-only-recipients.gamipress-switch label:after {
    top: 17px;
    left: 12px;
}

I couldn’t find out the way to fix #1.
Can you kindly guide me what could be the issue?
