ASC5 saved search, sometimes don't show up

I have a fair number of saved searches such as;

https://data.census.gov/table?q=S2201&g=050XX00US01001&y=2022&tid=ACSST5Y2022.S2201&moe=false

This was a 2021 search but I have a variable for the year, and I just update it to 2022 and they work fine (Except)

For some reason some don't work (error or blank), but sometimes if I play around with a new search, I can get it to work but the format of the search is different (although the numbers match).

https://data.census.gov/table/ACSDT5YSPT2021.B19055?q=B19055&g=050XX00US01001&y=2021&moe=false for 2021 works.

https://data.census.gov/table/ACSDT5YSPT2022.B19055?q=B19055&g=050XX00US01001&y=2021&moe=false for 2022 does not.

However,

https://data.census.gov/table/ACSDT5Y2022.B19055?q=B19055&g=050XX00US01001&y=2022&moe=false  Does (but see how the format is different).

What is the SPT, and why is it sometimes unhappy?

This has me a bit confused and although the numbers match my API call which still work, something is off?  I use my saved search to double-check some of my data to make sure the API and spreadsheet inputs\changes etc. match.  SO far about 30 work perfectly but 4 or 5 are funky.

Any thoughts?

Thanks.
