Shortcode by php. Doesn't search for media.

Hi,
I have question about plugin.
I’ve insert it by shortcode in “normal” WordPress page and it works perfectly, that was plugin what i was looking for.
But:
When I insert it by php function:

<?php echo do_shortcode('[mse-search-form]');?>

It sometimes is working sometimes is not. For example I put this code in “Search result” I want to put search form again when someone didn’t find photo what was looking for.

When You are searching from normal wordpress page links goes for:
example.com/?s=SEARCHTEXT&post_type=attachment

But when you put another text using Search Engine on mentioned above Search Results page, link goes for:
example.com/?post_type=attachment&post_type=attachment

Is there any option to make it works?
