This maybe caused by another module published on the page which has months as time dimension (not weeks)
All you need is a line item dimensioned by time (time formatted - month), a line item dimensioned by time (boolean) and a line item which you will use as a user filter (month). User will select month via this filter. And it will drive the boolean to match the month.
Month Li formula will have ITEM(TIME).
Boolean formula: Month Li = Filter
Then apply module with a filter by Filter Li
Also apart from that I'd recommend to check MONTHVALUE function.
Further to my question previously, I'm also unable to replicate the conditional formatting view.
I have added a line item as per my screen shot but struggle to replicate the conditional formatting. Moreover, how can the time line items be manipulated to create a filter that sets out the views as per the instructions in 2.4.7 (attached) with Initial Demand Forecast above Weeks and Month summarized by month given that they are all featuring in the line item dimension? How can I put this into the time dimension rather than the line item dimension?
Further to my note, when pivoting on line items, I'm unable to filter the time by month? I don't understand how the line item formulas can help replicate the view as in 2.4.7 is there a separate independent time dimension that helps consolidate the views by month and week rather than through the line item dimensions? I want to replicate the view as per the instructions in 2.4.7.
