When I go to SharePoint Site Contents-> K2 Five For SharePoint -> Manage App Deployments. It then throws a correlation id error. Checking the logs I get "An entry with the same key already exists". Please advice

Application error when access /_layouts/15/DeployTSApp.aspx, Error=An entry with the same key already exists. at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.TreeSet`1.AddIfNotPresent(T item) at System.Collections.Generic.SortedDictionary`2.Add(TKey key, TValue value) at Microsoft.SharePoint.ApplicationPages.DeployTSAppPage.AddItemToPicker(List`1 selectedItems, SortedDictionary`2 selectedItemsToAddToPicker, GroupedItemPicker picker, String id, String name, String description, String group) at Microsoft.SharePoint.ApplicationPages.DeployTSAppPage.AddItemsForLanguage(UInt32 lcid, SortedDictionary`2 selectedItemsToAddToPicker, Dictionary`2 alreadyAddedTemplates) at Microsoft.SharePoint.ApplicationPages.DeployTSAppPage.LoadSiteTemplatesPicker() at Microsoft.SharePoint.ApplicationPages.DeployTSAppPage.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
