Wrong URL site ID after duplicating

After duplicating one master site to 40 subsites I see a problem with several images.
The image HTML code points to the master site instead of the duplicated sites.

For example on the site testsite.nl/master-location/resources/extinguishing-media/ (ID 12) a image points to wp-content/uploads/sites/12/2019/07/Fire-hose-reel-150×150.jpg

But on a duplicated site testsite.nl/location10/resources/extinguishing-media/ (ID 39) the image also points to wp-content/uploads/sites/12/2019/07/Fire-hose-reel-150×150.jpg

Text editor URL: <img class="size-thumbnail wp-image-3367 alignleft" src="testsite.nl/location10/wp-content/uploads/sites/12/2019/07/Fire-hose-reel-150x150.jpg" alt="" width="150" height="150" />

Source frontend HTML code is:
<img class="size-thumbnail wp-image-3367 alignleft" src="testsite.nl/location10/wp-content/uploads/sites/12/2019/07/Fire-hose-reel-150x150.jpg" alt="" width="150" height="150" srcset="testsite.nl/location10/wp-content/uploads/sites/39/2019/07/Fire-hose-reel-150x150.jpg 150w, testsite.nl/location10/wp-content/uploads/sites/39/2019/07/Fire-hose-reel-300x300.jpg 300w, testsite.nl/location10/wp-content/uploads/sites/39/2019/07/Fire-hose-reel-768x769.jpg 768w, testsite.nl/location10/wp-content/uploads/sites/39/2019/07/Fire-hose-reel-1024x1024.jpg 1024w, testsite.nl/location10/wp-content/uploads/sites/39/2019/07/Fire-hose-reel.jpg 1278w" sizes="(max-width: 150px) 100vw, 150px">

What could be the problem and how to solve it?
