Can't show draw debug primitive for AnimNode

In my project I use ConsoleVariable in My CustomAnimNode for trigger AnimDrawDebugSphere/Line.

It used to be fine.But today I open my project again and the AnimDrawDebugSphere won’t work anymore.
I try the build-in LegIK node in the same project and type the console command a.AnimNode.LegIK.debug 1 but it still won’t work.
The DrawDebug for my C++/blueprint Character class work fine, but the AnimDrawDebugXXX won’t work.

So I open another project and test the LegIK,now the LegIK work correctly.I just confuse ,it’s there any project setting that will override the Debug Primitive for AnimNode so my project can’t show debug primitive anymore?

hello, don’t know what you saying,

but I got same problem
