Several exercises are not working properly

In Khan Academy (English), these exercises have been reported as not working. Just tested after importing them from Studio in a fresh Kolibri installation and confirmed the problems are in the latest version of the channel:

Math>2nd grade>Measurement and data>Picture graphs
Title: Solve problems with picture graphs 1
Content node: a9d614c61eaf58c19c690ac50e96e8a8
Problems:

• The exercise does not work: After entering the value and clicking on the "Check" button, it says "Please enter an answer above". No way to make it see the answer
• It makes one external request to draw the exercise https://ka-perseus-graphie.s3.amazonaws.com/d47d10ca9eb9419b40a372bddcbc88e3661bc4c9.svg

etc.

Math>4th grade>Geometry>Measuring angles

It makes an external request to draw the ruler: https://ka-perseus-graphie.s3.amazonaws.com/e9d032f2ab8b95979f674fbfa67056442ba1ff6a.png

Math>4th grade>Geometry>Angle types
Title: Benchmark angles
Content node:31183c76965854e994525b3225568a35
Problem:
There's no way to provide an answer or solution to the question. Without it, clicking on the "Check" button it says the answer is correct.

Confirm something is not right with this exercise in Kolibri: https://kolibri-catalog-en.learningequality.org/en/learn/#/topics/c/d0657c4d64fc51c9972c83fceb48a2d8

And it's a problem on our side, since the source exercise https://www.khanacademy.org/math/early-math/cc-early-math-measure-data-topic/cc-early-picture-graphs/e/solving-problems-with-picture-graphs-1 works fine.
