Pulling Description wrong

1. The plugin is pulling the meta description wrong – the description shown in the validation test looks like this –

<a title=”clothes in fashion” class=”read-more” href=”https://sitename/clothes in fashion/” aria-label=”More on clothes in fashion”>Read more</a>

What do I do for it to pull the correct description?

2. Does the plugin disable all other schema by default. Because I have disabled generate press schema and enabled rankmath sitelink mark up with this add_filter( ‘rank_math/json_ld/disable_search’, ‘__return_false’ ); – but i cannot find the searchaction field in the schema tests after enabling your plugin.

How to enable this ?

3. what is this field about –

Linked Open Data = Publish website schema.org data items as Linked Open Data

Thanks in advance
