The 31CAP and 31LCDA both have separate uses to resolve issues experienced with 2-wire Dimmers.
The 31CAP should be used when minimum load of the device is not being met, this is usually indicated by the load/light, that is controlled by the dimmer, by glowing when it should be off. Adding the 31CAP will increase the load and prevent the load/light from glowing in the off state. Depending on how far off minimum load you are more than one 31CAP may be required.
The 31LCDA should be used in instances where the load/light is flickering constantly, which indicates an issue with compatibility with the 2-wire dimmer used. The 31LCDA resolves these incompatibilities and flickering should then stop, if the flickering is reduced but still present you may need another 31LCDA to completely resolve. No more than 3x 31LCDA’s should be used on one dimmer.
