Calculated column doesn't expand the items in list view

Question

Dear All,
          I have a calculated column
Week with formula, =INT((DAY([Start Time])+6)/7) 
in one of my lists. I'm displaying a view of this list in a SharePoint page, group by column Year and column
Week. But when the page is loaded with items, I'm only able to expand the list view up to
Year column level. When I click on Week section it doesn't show / expand the items under it.
Further more when I use a different calculated column with a function like (=TEXT(Date,"yyyy")) I don't get above error.
Any Idea?
Thanks,
Dilip

Hi Dilip,
According to your description, an issue occurs when you try to expand the subgroups in a list contains Calculated column.
It is an known issue in SharePoint 2013, there are some workarounds I can provide as below:
As the first workaround, you can set the groupings to expanded by default, though it would make the grouping collapsed by default, then the grouping would function
normal.
As the second workaround, you can create a SharePoint Designer Workflow and add a “Do Calculation” action to calculate the value you needed. Then add a “Update List
Item” action to add the value to a “Single line of text” column. We will use the “Single line of text” column in the grouping instead of the Calculated column.
As the third workaround, you can install the latest update of SharePoint to fix the issue for new Document Libraries. For the existing libraries, after the installing
the update, you can use PowerShell to make an update to each item in the library, it will make the old items get normal in the grouping.
About how to update list items in a list/library using PowerShell, a demo as below for your reference:
$web = Get-SPWeb http://YourServer/
$list = $web.Lists["list name"]
foreach ($item in $list.Items)
$item.SystemUpdate();
