The main problem I see is that there's a significant amount of oxidation/corrosion buildup on many of these Control Rods. Now the Actuator Rods (and buttons) are not necessarily the only thing to focus on here. Underneath all this stuff, lying next to the wood is a Network of Control Rods, which are packed together very closely. When one or more are corroded (like this) they will NOT rotate freely in their seats. Hence they become Sticky. I had the exact same problem on a Crucianelli that I restored. The previous owner tried squirting 'Lube' down in there, but that makes it worse over time. The only Long-Term solution is to break the Bass Control-Section down all the way and remove the corrosion from the Rods, then perhaps (like I did) Cold-Blue the Rods, then reassemble. Mine has no more sticking Bass-buttons now, and operates perfectly. Be Advised: This is not an easy job. It's Very involved.
Straighten the bent button. Take apart the bass actuators and clean them with a contact cleaner only if the buttons are still slow. Light corrotion is fine its to be expected.
It appears that the rod is bent. I have seen this condition fixed by sliding a tube over the button that has an inside diameter of just slightly larger than the button and bending it until straight. You don't need to open the back. I'd give it a try.
