Module does not always show in child page

Hi

I often use an edocman module in the side bar.
When a user clicks a category in the sidebar module I want the module to remain in place on the child page.

I put the parent menu ID in the Itemid box
 

But the module does not always show on the child page.
For example, if you go to  corleyvillage.org.uk/parish-council/meetings
Then click one of the categories on the right hand side bar (i.e. 2023 Minutes)

 

I want the module to show on the page it take you to, but it does not.

 

Can you help me resolve this please?

Thanks
Alison

Hi Alison,
I am not sure the menu Item ID 152 is the menu to Edocman layout. Could you please submit ticket on category: Edocman and provide your site credentials. I will figure the issue for you
Thanks
