The church has always had a unified stance on this, but there are a lot of priests out there, and many of them will go rogue at times. You’re seeing it with Catholic leadership in the US right now, especially over politics. Being a diehard supporter for Trump and being a Catholic is becoming a much more difficult tightrope to walk because it often backslides into rejecting basic social norms and human decency. Notice how he just removed a bishop who had become particularly loud lately.

Basically, it’s impossible to audit every single priest, bishop, deacon, cardinal, etc. out there and make sure they are 100% nailing everything exactly right. The church kind of dragged its feet on LGBTQ issues even as they were rapidly changing in the world, so naturally some people started taking it upon themselves to give it their own individual spin and went a little more hard line or loose. That stuff tends to shake out overtime as the church makes its existing stance clearer or clarifies how to apply it to new situations - often in response to deviation.
