Personal Message notification showing incorrect reply count

Hi everyone!
I’m sending a private message through the user api. using the username ‘system’’

 const postData = {
        title: messageTitle,
        raw: messageBody,
        username: 'system',
        category: 22,
        target_recipients,
        archetype: 'private_message',
        is_warning: true,
        status: 'archived',
        enabled: false,
    };

    // start sending message
    try {
        const response = await fetch(endpoint, {
            method: 'POST',
            headers: getHeaders(),
            body: JSON.stringify(postData),
        });

        // Convert the response to JSON
        const data = await response.json();
        return data;
    } catch (error) {
        return { errors: ['something went wrong while sending PM'] };
    }

However, in the notification, it’s showing ‘2 replies’

But there are actually no replies


What’s even stranger is that this issue only occurs when I send a PM from the live site. Testing from localhost does not trigger the problem.

Any idea?

Hi, Anyone was able to reproduce?
