Missing category label on pie chart

Unlike Bar or Line graphs, there aren't as many 'Detail Labels' formatting options for pie charts in PowerBI.  There are many data visual professionals who would tell everyone to use the pie chart as a Last Resort because it has several pre-attentive limiiations, but if you have to use it consider two options below:  

1:  Since your Legend is right next to your pie chart, consider changing the Detail Label formatting to Data Value.  You don't need to tell them again what the Red color means if the meaning is right above it...

2:  If you make your visual a little bigger, the name would fix as well.

Personally, unless you are directed to do so, I would try to avoid the pie chart.  In your example, if I was to ask 'which is bigger Shop or Testing, it would be very difficult to tell?  Consider a Multi Row Card to make these values pop since your 2nd and 3rd values are so close to each other and so far away from your first value.

Lastly, you can always suggest an improvment to Power BI to improve placement options of Detail Labels on Pie Charts.  

Thank You,
