Follow up transaction pop up is not showing for IR

HI Experts,

Please could you help on this below issue:

We are creating follow up activity for Interaction record.

I am able to see my follow up transactions in  Transaction Type drop down in IR but when I select my Activity and click on "Create Follow-up" button,

there is no pop up screen and it is not directing to Activity creation screen but it is displaying "Follow-up transaction was created".

I have done copy control between my IR and Activity but it is not bringing me to Follow up activity screen.

Thanks

Madhu
