Upheaval with avalanche and Rejuvenating Splinters

Large Avalanche Boulder doesnt cast Upheaval consequently and Upheaval cast this way dont trigger Totems to explode.

Skills: Tempest strike, Avalanche, upheaval
Skillnodes: Excavation, Intensity, Rejuvenating Splinters
Items: Heretical ornate Idol
Affix: Avalanche Bulder on melee hit, Thorn totem on hit

What i expect:
With my melee hits and small avalanche boulders i get thorn totems, which explode once when a large boulder drops and triggers upheaval.

What is happening:
Thron totems, smal boulders and large boulders (with elemental spawn) happen exactly as planned. but neither do i get my upheaval trigger with every large boulder (though 100%) nor does the upheaval cast this way let my thorn totems explode. On normal attack, i do get thorn totems from the hit and they explode the secon upheaval or shockwave hits em (often resulting in new totems)
my scorpion gets his large boulders and upheavals, but they dodnt trigger totems to explode
