TMSMQTT Client Keeps on receiving the last payload

Hi,
I'm using TMSMQTTto send information from one program to the other.
I keep on getting the payload every few seconds.
I'm using TMSMQTT to send as well but the problem is not from sending multiple times since the program that is in charge to send the Payload is long closed and I keep on getting new ones.

The QoS is set to atMostOnce so it should get more. (I tried setting it to ExactlyOnce but It couldn't connect...)
The Retain option is also unchecked so I can't figure out what this weird issue is.
See Screenshot of Properties below.
