plugins – Unable to find inline CSS inflicting components of web page to be clean

Massive components on a reside WordPress web page reveals clean as a result of a chunk of inline CSS has opacity set to 0. Sadly I’m unable to search out the place this inline CSS lives.

<div class="grve-element grve-text vc_custom_1655582827387">
    <div class="ptsTableFrontedShell">
    <!-- Fashion to show all tables correct-->
    <!-- this block shall be take away in frontend.tables.editor.block.base after init -->
    <div class="ptsPreDisplayStyle">
        <type>
            .ptsBlock {
                opacity: 0;
                visibility: hidden;
            }
        </type>

vc_custom refers to Visible Composer which apparently now’s WPBakery. Provided that info I seemed into the Row, Column and Textual content Block settings when modifying the web page with WPBakery however could not discover any customized CSS.

Concerning ID 1655582827387, I’ve no clue the place to start out trying to find this ID. Lastly, it is unclear to me the place the category ptsBlock comes from.
