...a brief addendum...
I also tried:
a) changing the rating range to "1-4000", "1-10000", etc, but was still unable to access the 4th & 5th puzzles, or do them again...
b) this is not specific to the "exch sac" theme. Had the same issue(s) with "perpet", "stalemate", "interference", etc.
JD - Can you give us an ETA on this and the other learning mode bugs?
FYI, these bugs are not exclusive to BETA. I encounter the same issues outside of BETA too.
Thanks.
It is very possible the puzzle that didn't show have been removed from the available puzzles.

It's not just the puzzle used in the example. This (and the other learning mode bug) happens regardless of theme and/or rating range.
1) On https://www.chess.com/stats/puzzles/username, hovering over the exchange sac theme:
shows 5 puzzles failed.
2) at https://www.chess.com/puzzles/learning, select "exchange sac", "problems I have failed", and rating range of "1-3000":
3) was presented with 3 of 5 puzzles, but when I tried to click the "next puzzle button" to go to the 4th of 5, the cursor was changed to:
... and the next puzzle button was unresponsive.
4) On my stats page, I can see that I did 3 exchange sac puzzles in learning mode, but could not access the 4th & 5th in learning mode.
5) Went back to https://www.chess.com/puzzles/learning, and refresh the page. All settings remain the same (see #2 above), but when I click on "start", was presented with the bug reported here.
Suggested fix: All failed puzzles should be presented to users in learning mode, not just a select few.
