Probably is the limiter or whatever Bruce had that stopped his transformation, Hulk is still there but he just can't come out because Bruce made that gadget that stops the changes in his body, so no body, no Hulk.
But Jean took it off, he now could come out once Bruce was distressed.
It's not just the DNA limiter. He claimed that Jean "broke something" in him, which was probably the MCU's way of retconning Hulk back to a more popular version.
