I have found a glitch, and I couldn't find anything but this forum to post the issue https://gyazo.com/b3758b37dcf6f6e2a10391466c715de2 Had been running. Is used twice in the past perfect progressive tense test.
The link you provided does not work. PaulM
Apology, you must copy it.
Yes, it is shown twice, but I don't know why. PaulM
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. PaulM
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. http://www.grammar-monster.com/glossary/past_perfect_progressive_tense.htm Copy the link.
