Bloodhound discards suggestions fetched from remote

[JakupGuven]

I have an issue with a specific search string where Bloodhound receives four elements from remote that I'd like to have displayed as suggestions.

Instead only one suggestion is displayed.

I can tell that the elements are actually received by Bloodhound by making a custom transform simply displaying the response.
However when I don't define a custom transform some where along the way the would-be suggestions dissappear.

UPDATE:
After further debugging I've discovered that the elements are still present after
function processRemote(remote)
is called.

source: new Bloodhound({
                        datumTokenizer: Bloodhound.tokenizers.obj.whitespace('Title'),
                        queryTokenizer: Bloodhound.tokenizers.whitespace,
                        remote: {
                            url: '/api/suggest/' + p + '/%QUERY',
                            wildcard: '%QUERY',
                            //transform: function (response) {
                            //    console.log(response)
                            //}
                        },

                    }),
                    templates: {
                        header: '<h3 class="league-name">' + data[p].charAt(0).toUpperCase() + data[p].slice(1) + '</h3>',
                        suggestion: function (d) {
                            return "<a href=" + d.Url + "><span>" + d.Title + "</span></a>"
                        }
                    }
                };

Did anyone experience similar issues?
How can I solve this?

These are the elements.
Only the first one ends up being displayed.
