This happens all the time. I’m a regular player who just tries to get a keystone every week, but 9 out 10 times, I don’t. But everyday I run BiB and it’s tell me I need to switch gear out, or buy another 4k gold enchant or gem. Been running BiB everyday for literally years. Why the daily differences in AMR recommendations to equip your toon with the best configurations. It seems to change change single everyday,and it’s costing me 1000s of gold every week.
I would need specific examples to answer this. In general, we have designed the site specifically to avoid what you are describing.
Do you have gem and enchant and azerite thresholds disabled? You could try increasing that threshold as a first step.
