PHP Warning: Missing argument 4 for FinalTilesGallery::__construct()

Thanks for the great plugin! we did notice this in our logs. when additional pages are loaded, this error happens:

PHP Warning: Missing argument 4 for FinalTilesGallery::__construct(), called in …/wp-content/plugins/final-tiles-grid-gallery-lite/FinalTilesGalleryLite.php on line 1190 and defined in …/wp-content/plugins/final-tiles-grid-gallery-lite/lib/gallery-class.php on line 7

I patched my plugin, but would prefer if the fix can be also added to the plugin, so when I get updates it will also be there:
