Greetings! Fret not, the objectives are expected to be retroactive after next week's mid-season patch, as per a [url=https://twitter.com/Destiny2Team/status/1645931852551839750?s=20]Destiny2Team tweet[/url]. [quote]🚨Solo and Master dungeon/raid completions not being retroactive for Guardian Rank 11 is not intended! We have a fix for this in our midseason update which is currently scheduled for next week. It will be retroactive, so you won't need to complete the objective again. 🚨[/quote] Just make sure you claim the Triumph for your solo/Master completions when the update goes live.

Seems like a bug. Almost all objectives for Rank 11 has been retroactively completed (save for the commendation score as mentioned in the Reflecting on Lightfall article), but my solo clear of Spire of the Watcher hasn't counted for the Solo Spelunker objective.
