ESP8266 sends data alternately

[scaevola]

Hi there,
I have an ESP8266 with two DS18b20 thermometers connected. I configured ESPeasy to send data from the DS's to Thingspeak. Everything would be ok (data is received by the server), but ESP sends data alternately, this means, only one temperature per connection, the second value is empty. Once it sends from the first DS, after 30 seconds from the second DS.
Did I configured something wrong? Why it can't send both values at once?

The problem is when I try to work with data on matlab when I import data from channel, it says that one of the values is NaN (not a number) - and so it is, as ESP sends the data every other connection.
How to configure ESP to send data in one transmission?

Greetings,
