Questions about ARM Keil uvision5 debug features

Excuse me for asking a question. In the debug function of ARM Keil uvision 5, when you add a new variable (in this case q16_theta_2) on the watch as shown in the image below, only the variable name is added, no value is added, and it appears to be shifted one step (as if the value of q15_vdc_ave is entered in q16_theta_2). Do you know anything about this phenomenon?
