OJS 2.4.8 Issue with Auto emails

Hi, i am having a issue with the prepared emails.

When you select a reviewer they received this prepared email: REVIEW REQUEST ONECLICK .

But the last time a reviewer received 4 emails before this.

The auto emails were REVIEW REQUEST REMIND AUTO ONECLICK.
And maybe this too REVIEW REQUEST REMIND AUTO, I am not sure

First: I dont understand when this auto email activates.
Second: i Think that this 2 auto emails were send because the journal have this configuration.

Any comment or suggestion of what can i do will be well received.
