Sounds like the process was not done well at your company. I have my OKRs set up so that I spend almost all my time working on them. I do usually have one or two "personal OKRs" like the one you described, but most of them represent the team's core work: "put major feature X into production", "address P1 customer issues with 3 days", whatever.
It gives you a nice defense when some seemingly urgent but less important work comes along. "We could do that, but it would cost us this OKR which we agreed at all levels was one of the most important things for our team to do."
