Forum topics all show "4 replies" in the summary list, regardless of the actual number

As shown in the attached screenshots, every forum topic in the list is showing as having "4 replies", regardless of whether it actually has 1 reply, 2 replies or any other number as shown when opening the topic. I've only just noticed this problem, and clearing my browser cache or using a different browser doesn't fix it, so I think it might be a glitch at Zoho's end. It's not a serious issue but perhaps you could have a look? Thanks.

[edit: strangely this topic itself doesn't shows as having any replies - which is correct. Perhaps it's only topics that have at least 1 reply that show the "4 replies" problem]
