Padding field blued out in Flex Box 3 – cannot change

Hello – critical padding fields in tablet and mobile views in Flex Block 3 are blued out and cannot be changed – see the screenshot here: https://drive.google.com/file/d/14vW2kNTJ2DANqj8x13MsNNI9i1Vdh3ZL/view?usp=sharing

They are still white in desktop view. The website is https://jazzjournal.co.uk

I have tried changing these parameters on two machines, but they are blue on both.

I’d appreciate urgent reply.

Thanks, Mark Gilbert

More – in tablet horizontal view the lower vertical padding is inheriting the padding in desktop view and not changeable. If I change desktop padding, tablet padding changes too and is locked to same padding as desktop.

Padding is locked in many other Flex Box 3 across the site.

I have fixed this one instance “39” by going to Inspect Element and changing

<input data-tdc-for=”padding-bottom” name=”” type=”text” value=”52″ class=”tdc-css-box-input tdc-css-box-input-padding-bottom” title=”Css padding-bottom” placeholder=”39″ data-model_id=”c17″ data-param_name=”tdc_css”>

to

<input data-tdc-for=”padding-bottom” name=”” type=”text” value=”52″ class=”tdc-css-box-input tdc-css-box-input-padding-bottom” title=”Css padding-bottom” placeholder=”-” data-model_id=”c17″ data-param_name=”tdc_css”>

but I am not a coder and have no idea what I’m doing. I guess these uneditable placeholders are the problem – but why have they appeared and is there a global fix?
