When the card is relearning (which are searched by is:learn is:review), the Interval info at the upper part of Card info doesn’t seem to work properly.
Incidentally, I’m wondering what you think of the idea of replacing the Interval label of the study history with another one which is potentially able to include both Interval and Step, such as Delay, Space.
I’m not sure what the best choice is here. “Interval” can be used in the generic sense to be a period of time, and also in the Anki card-specific sense of “a review interval”. Using something like “delay” might better contrast with the latter use of “interval”, but I’ve seen some people comment in the past that they didn’t like the word “delay”. A better change might be to change “interval” to “review interval” in the card info screen, or at least document it.

Though it may be flexibly acceptable to be polysemous as a word in explanation, but it might be less acceptable to be polysemous as an item name.
Moreover, the term, ‘interval’, seems to be used consistently as the Anki card-specific meaning on Browser and Deck Option and Card Info screen, except for the label in the study history. So, to replace the label and unify the usage of “interval” might be meaningful even if the new label would be somewhat less attractive.

At first, the “review interval” did sound good, but on my second thought it may not, because “review” is also equivocal in the info screen (and in whole Anki). I mean, in the info screen, “review interval” might not be helpful enough to guide users to the Anki-specific meaning because it would be surrounded by the general sense of “review”.

Actually, I somewhat share that feeling.
How about “Spacing”. It might harmonize with the neighboring label, “Rating”.
To re-state @snowtimeglass’s point: “interval” is used at the top to only refer to the delay in review mode. “interval” is used at the bottom for the period of both learning + review cards.
