google maps in quelltext even when street maps is activated?

I am checking my site speed and wonder about https://maps.googleapis.com/maps/api/js?key&libraries=places&ver=6.2.1 with 39 kb . When checking quelltext I find this <script src=’https://lebenindenusa.com/wp-content/uploads/siteground-optimizer-assets/atbdp-popper-script.min.js’></script&gt; <script src=’//maps.googleapis.com/maps/api/js?key&libraries=places&ver=6.2.1′></script> <script src=’https://lebenindenusa.com/wp-content/uploads/siteground-optimizer-assets/atbdp-markerclusterer.min.js’></script&gt;

I could be totaly wrong, I am not a pro. But it looks for me because of the …atbdp… that there is something with googlemaps from the directorist.

Also when I dektivate on single listing the google map, map on single listing (what should be open street) disapers.

And a second little thing is when clicking on the button “view as” on the listings page, you have to klick twice. Not a bigy, but would be better by one click.

Any recomandations apprichiated
