IOCs and TTPs extracting and identifying. Malware tab issue

For the IOCs and TTPs: Extracting and Identifying lab its asking me to get to the malware tab and it looks like theres suppose to be a scroll wheel to get to the malware tab but its not working at all, it may not be that but it only shows up when I get to that part and its unresponsive. Not sure where to go from here I've tried refreshing, clicking inside the panel, zooming in and out, using ai, looking online and none of it has worked. 

Before I get to the steps as you can see no scroll wheel under credentials tab.

Now that I'm in the questions it shows what looks like a scroll wheel under the credentials tab:

Anyone that can help please do, thanks.
