Thanos Take no damage from sp3 When Indestructible is off

I face Thanos in master quest with CAPIW.
In the next video, you will see in slow motion that I removed the indestructible buff and triggered sp3. The damage I did was 1% with rank 5 CAPIW with Kinetic charges.
Please pay attention that before sp3 he had no indestructible and after sp3 he still had armor breaks and no indestructible

There is noting in Thanos abilities that should cap the damage:

Definitely seems to be some weird interaction with Cap IW's special 3 and this Thanos

his safeguard from phase 2 was still active in last phase and was capping the damage, hence the 1% damage with beardo
