Issues with circulating between placeholders

[Trid-collab]

I am using Neovim stable with nvim.cmp and cmp-nvim-ultisnips But noticed that the I am not able to circulate the snippet placeholders using tabs like it was working before. Its not even working in the neovim stable release. When I am typing in the snippet placeholder the autocompletes are popping up while I am typing. On completion I am not able to use the tabs to move to the next placeholder.

This working earlier before -few days back This is my mapping setup. I am sorry I am no expert on this. Just tried to follow some leads which I picked up while going through the configs of others and it worked for me till recently

mapping = {
	["<C-p>"] = cmp.mapping.select_prev_item(),
	["<C-k>"] = cmp.mapping.select_prev_item(),
	["<C-n>"] = cmp.mapping.select_next_item(),
	["<C-j>"] = cmp.mapping.select_next_item(),
	["<C-d>"] = cmp.mapping.scroll_docs(-4),
	["<C-f>"] = cmp.mapping.scroll_docs(4),
	["<C-e>"] = cmp.mapping.close(),
	["<CR>"] = cmp.mapping.confirm({
		behavior = cmp.ConfirmBehavior.Insert,
		select = true,
	}),
	["<C-Space>"] = cmp.mapping(function(fallback)
		if vim.fn.pumvisible() == 1 then
			if vim.fn["UltiSnips#CanExpandSnippet"]() == 1 then
				return vim.fn.feedkeys(t("<C-R>=UltiSnips#ExpandSnippet()<CR>"))
			end
			vim.fn.feedkeys(t("<C-n>"), "n")
		elseif check_back_space() then
			vim.fn.feedkeys(t("<cr>"), "n")
		else
			fallback()
		end
	end, {
		"i",
		"s",
	}),
	["<Tab>"] = cmp.mapping(function(fallback)
		if vim.fn.complete_info()["selected"] == -1 and vim.fn["UltiSnips#CanExpandSnippet"]() == 1 then
			vim.fn.feedkeys(t("<C-R>=UltiSnips#ExpandSnippet()<CR>"))
		elseif vim.fn["UltiSnips#CanJumpForwards"]() == 1 then
			vim.fn.feedkeys(t("<ESC>:call UltiSnips#JumpForwards()<CR>"))
		elseif vim.fn.pumvisible() == 1 then
			vim.fn.feedkeys(t("<C-n>"), "n")
		elseif check_back_space() then
			vim.fn.feedkeys(t("<tab>"), "n")
		else
			fallback()
		end
	end, {
		"i",
		"s",
	}),
	["<S-Tab>"] = cmp.mapping(function(fallback)
		if vim.fn["UltiSnips#CanJumpBackwards"]() == 1 then
			return vim.fn.feedkeys(t("<C-R>=UltiSnips#JumpBackwards()<CR>"))
		elseif vim.fn.pumvisible() == 1 then
			vim.fn.feedkeys(t("<C-p>"), "n")
		else
			fallback()
		end
	end, {
		"i",
		"s",
	}),
},

My plugin setup

use({
	"SirVer/ultisnips",
	requires = { "honza/vim-snippets" },
	config = function()
		vim.g.UltiSnipsRemoveSelectModeMappings = 0
	end,
})
