Data "azurerm_shared_image_version" with "latest" is not checking the version

We have following coded in our deployment pipeline:

data "azurerm_shared_image_version" "image-ver" {
	provider				= azurerm.SIG
	name 					= "latest"
	image_name              = var.SIG_Definition
	gallery_name            = var.SIG_Name
	resource_group_name     = var.SIG_RG
}

Initially it did pickup new image and built VM with new image while re-deploying.
Somehow, now its not picking up.

Here is how our image listed on shared gallery:
Screenshot of a list of images with names all starting with prefix OHG_19.3.0.0.0_RHEL8_ followed by a timestamp

Any help is appreciated.
