Where is Frame Data? Peculiar Jab Situation with Bryan & Master Raven

Here's a interesting interaction in Tekken 7 Fated Retribution. If you're Bryan up against a opponent using Master Raven, the most basic of frame trap situations don't seem to occur as naturally as you would expect. Considering that jabs in this game are 10 frames on start-up, it seems that even in disadvantageous circumstances, Master Raven's will override and beat Bryan's jab. To be more specific, if after certain plus frames on block moves like Bryan's jab (+1 on block), b+1 Chopping Elbow (+3) and the qcb+3 low soccer kick (+4) hit, both players doing a jab will make Master Raven win here. It's all hard to picture when reading so here are the video findings that both Knee and Low High have shared on this interaction. Is it bugged or is there a finer detail in play here? Where is frame data.

I don't understand, Why does this problem occur? where is frame data?
