Equal consecutive learning interval collapsed during studing session.

With Anki 2.6.1 (just updated to 2.7 and have no opportunity to check on new version) if

hold on desk
select Deck options
select New Card
select Steps (in minutes)
enter 5 1 1 1 1 1 1 1 20 or similar pattern
leave out of all option menus
start learning new card

After showing card I type Good (1 min), after 1 min I have only choice to type Good (20 min). All equal learning intervals collapsed into single and I am prompted to check next non-equal interval.

NOTE Red indicator of card in learning correctly updated after checking Good (20 min). So if I have seven 1 min intervals it decreased by 7 ))

New research http://learninglab.psych.purdue.edu/downloads/2011_Karpicke_Bauernschmidt_JEPLMC.pdf showed that there is no any improvements with using increasing delays between showing cards (for learning during the day). Only repetition count and total session duration have role (the more is better). I started discussion on this topic at http://languagelearning.stackexchange.com/questions/2344/repetition-interval-during-initial-learning-within-a-day and https://www.reddit.com/r/Anki/comments/57zdtu/what_learning_steps_interval_you_used_for/

I try to use divide duration of my typical learning session into equal intervals and trapped to this error.

I actually use 5 15 15 15 120 pattern. I should see card 3 times during in my typical 1 hour session and later see it in the evening or next day. But I see it only once.

As word-around I set interval pattern to 5 20 15 10 120 which work as expected.
