How can I avoid the superfluous creation of uniqueIDs and classes?

Hello everyone!

We are currently building a website that shows many sayings and quotes with corresponding pictures. I want the output of the code of this picture text compound to be as slender and simple as possible. The design of the pictures is defined centrally in the Global Styles. However, each combination …

1) initially creates its own uniqueID (in the example: "9e9aad85")
2) creates another uniqueID at the picture (in the example: "5a2cde0f")
3) creates yet another class, which receives its own combination of letters and numbers each time (in the example: "gb-image-5a2cde0f")

This is an example of such code:

<!-- wp:columns -->
<div class="wp-block-columns"><!-- wp:column -->
<div class="wp-block-column"><!-- wp:generateblocks/container {"uniqueId":"9e9aad85","paddingSyncUnits":true,"isDynamic":true,"blockVersion":2,"useGlobalStyle":true,"globalStyleId":"spruchbild-links","globalStyleLabel":"spruchbild-links"} -->
<!-- wp:generateblocks/image {"uniqueId":"5a2cde0f","mediaId":4759,"sizeSlug":"full","globalStyleLabel":"spruchbild"} -->
<figure class="gb-block-image gb-block-image-5a2cde0f"><img class="gb-image gb-image-5a2cde0f" src="https://gruesse-wuensche.de/wp-content/uploads/guten-morgen-spruch-wie-eine-uhr.jpg" alt="Eine Uhr für den Spruch: Ich bin wie eine Uhr" title="Spruch: Ich bin wie eine Uhr"/></figure>
<!-- /wp:generateblocks/image -->
<!-- /wp:generateblocks/container --></div>
<!-- /wp:column -->

<!-- wp:column -->
<div class="wp-block-column"><!-- wp:quote {"className":"zitat-autor"} -->
<blockquote class="wp-block-quote zitat-autor"><!-- wp:paragraph {"className":"zitat-medium"} -->
<p class="zitat-medium">Ich bin wie eine Uhr,<br>die sich jeden Tag von neuem<br>richten muss, weil sie jeden Tag<br>immer wieder von neuem nachgeht.</p>
<!-- /wp:paragraph --><cite>Christian Morgenstern</cite></blockquote>
<!-- /wp:quote -->

<!-- wp:paragraph -->
<p>Humorvoller Guten-Morgen-Spruch für Tage, an denen man sich erst mal wieder zurecht finden muss. Tipp: gut geeignet für WhatsApp, wenn Sie sich einmal verspäten.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"className":"sprueche-id"} -->
<p class="sprueche-id">Spruch-ID: 1923</p>
<!-- /wp:paragraph --></div>
<!-- /wp:column --></div>
<!-- /wp:columns -->

If I remove these 3 superfluous elements manually, I'll receive an error message upon pasting the code again, since WordPress seems to expect this information.

Could you please help me to find out if – and if so, how – I can remove these uniqueIDs and superfluous class in a way that will not result in an error message?

Best wishes,
Betina
