I was upfront but it isn’t do… can you help me?
That looks to me like your print bed (that metal plate you show in your picture) is not flat against the bottom of the resin VAT.
You need to make sure that the top of the Titan is level in both directions AND make sure the print bed is level as well. Another way to do it is to ensure the top of the Titan is level, loosen the ball joint on the print bed a LOT, loosen the 4 screws on the lever holding the print bed against the up-down pole, and then bring the print bed down to the VAT (as per the instructions for the machine, where you hold the lever up, since it is now slightly loose). When you get to the lowest point, you then make sure the print bed lays very flat against the bottom of the VAT before tightening all the screws and ball joint.
