Issue LAB: Lab: Configure user resource limits and user privileges

I encounter some problem:

Question 8, impossible to pass the question, even if my response was correct

Same situation for the question 11

to resolve this bug, i had to copy and paste the text of the solution, even if i had the right answer

i also encounter some problem in the first LAB: Files, directories, hard and soft links, but i can’t remember the question

There is also a bug in Lab: File content, regular expressions

Question 11, i need to move a line from position no:1049 to position no:5, but the target line is in line no:1057

And i can’t report directly on the lab because I get stuck in screeshot mode-like and i can’t do anything, neither exit or take a screenshot, the only way to quit this position is to reload the page
