Error: conversion from float to int loses precision

I'm seeing a TON of errors in my debug logs like this:

Implicit conversion from float 999054.9087524414 to int loses precision

Plugin: FluentCommunity Pro

File: /wp-content/plugins/fluent-community/app/Hooks/Handlers/EmailNotificationHandler.php Line: 564

The float varies, but there are thousands of entries in my debug log of the same type of error.

Can we get someone to look into this and see if we can get it sorted?
