Running geogrid under uplift load in PLAXIS 3D

I am investigating the failure mechanism of the belled pile embedded in geogrid-reinforced sand under uplift load in PLAXIS 3D current version. However, I can not run the geogrid in the model I have installed. In my previous work, I investigated the uplift behavior of the anchor plate embedded in the geogrid-reinforced soil in PLAXIS 3D TUNNEL version and saw the effect of the geogrid in both capacity and failure mechanism. However, in the new version of the software, I could not operate the geogrid under the uplift load although I'm doing updated mesh. I have reviewed the previous posts/papers about geogrid in the forum and based on the studies, I tried to make the geogrid anisotropic and set the GA to zero, but still, the result did not change. Why can't I run geogrid on uplift load?
