I have found a glitch, and I couldn't find anything but this forum to post the issue
Had been running. Is used twice in the past perfect progressive tense test.
The link you provided does not work.
Apology, you must copy it.
Yes, it is shown twice, but I don't know why.
Unfortunately, its a glitch, is there any way I can contact the Grammar monster team for this issue?
Are you saying there's an error in GM? If so, can you provide a link to the relevant page.
past perfect progressive tense test is the glitch I found, it is a simple glitch because there maybe not enough questions to fill in.
Apology for the long response.
Copy the link.
