listMessages not working when messages are unread

I am using listMessages to go through all message in my inbox. This worked when all messages were unread. Now I have had the code execute once and set all messages to read; now I occur bugs

async function page (pagesize, number) {
    var start = pagesize * (number-1) + 1;
    var end = start + pagesize -1;
    var range = `${start}:${end}`;
    //var range = '1:1';
    logger.info("Getting Messages " + range);

    var messages = [];
    try {
         await client.listMessages('INBOX', range , ['uid', 'flags', 'envelope','bodystructure', 'body[]']);
    } catch (err) {
        logger.error("Error getting Messages: " + err);
        return messages;
    }
}

Now I have mostly unread messages, and here comes the error:

The Messages 1-10 that I try to read, they are all read, and it appears that listMessages first searches for ALL messages (FLAGS (\Answered \Flagged \Deleted \Seen \Draft)); and then it does not return any.

If I want to list all messages, then this messages should either show up completely in the query; or message 1-10 should return the first 10 unread messages.

I believe that I have found out a bug.

I should add, that after all pages are parsed, not one email is received. Even though there are unseen emails in the mailbox. This is the last page that I got; and I believe that this emails should be unseen (I have verified that there are unseen emails via webmail)
