Expert advisor chart icon stays blue without the red or green icon when offline or live



I am hoping someone can help with regards to expert advisors in MT5. I have purchased an EA and enabled algo trading but regardless of the expert advisor I add to my chart the EA icon in the top right of the chart remains blue without the green icon to show the EA is running, as can be seen in the image below.

I'm hoping someone can point out something obvious I'm missing as I've been searching for hours to try and fix this
