Trading post currency loop every time I log in

Today every time I login into my character, it says that I have currency in the chest and I open it and I’m supposed to have 500 coins but I only have 25 and it just keeps repeating every time I log in and out. I finished the progress yesterday got the mount and everything. If I’m not supposed to collect any more coins until the next month’s trading post reset then why am I still getting it in the chest and why is it not counting and looping? Is this a bug?
