Is possible to perform an "arm triangle" from half guard in online career mode?

Hi guys! In online career mode, my character has 5 starts in arm triangles and 5 stars in submission offensive. However i cannot perform arm triangle from half guard but only from full mount. Is it a bug?

In offline career or other game modes (for example fight now using Khabib) i can perform arm triangles from half guard without problem

Any suggestions?
