URL path typo for stylesheet loaded in Admin

The path for the queued stylesheet zm_zohomail_style-css used in admin mode has a double-slash in the URL string.

In code inspector html rendered is:

<link rel="stylesheet" id="zm_zohomail_style-css" href="https://website.name/wp-content/plugins/zoho-mail//assets/css/style.css?ver=1.0.0" type="text/css" media="all">

Note the ‘//’ between words ‘zoho-mail’ and ‘assets’.

Still functions but not normal ??
