Triac firing problem

Triac firing problem

(OP)
Hello, I'm having problem with triac firing and I have no clue what may be.

Please, check the attached link for more details (LTSpice).

When I trigger Vbc phase I get Vab conducting as well. Tried to build a simulation but is not converging yet.
Any help will be appreciated.

Sincerely
