I've been using HelloTalk for a while now, and one correction I got was that
「manga series)って聞いたことがありますか？」 was wrong, and that the correct way to say it is
「(manga series)って聞いたことありますか？」

I understand basic grammar, but I've never been able to figure out why I
sometimes see this grammar point written as 「たことがある」and other times written as
「たことある」. Is there some kind of nuance here, or? I understand that particles
are sometimes dropped, but is there a reason behind the が not being used here?

This was the post, though for the って I accidentally wrote it as が and was
corrected before I could edit it in my original post. I'm terrible when it
comes to proofreading. Anyways, I have no idea about the other correction. I'm
sure I made multiple other blunders in my post that weren't corrected, but
here it is:

>
> 今日はハイキングに行く予定だったけど、1日中雨が降ったり止んだりしています。結局家で漫画を読んで1日を過ごしました。もう一度PandoraHeartsを読みました。とても面白いシリーズだと思います。PandoraHeartsのアニメも好きだけど、アニメよりも漫画の方がずっといいと思います。次回、日本語で読んでみるつもりです。

question
grammar
Why is there no が in って聞いたことある
> XXって聞いたことがありますか？

I don't think your sentence is wrong. It sounds good to me.

* * *

I think they made the correction probably because って sounds colloquial while
たこと **が** ある does not.

> XX **って** 聞いたことありますか？

↑ って and ことある (omitting が) are both colloquial.
