I do not think that it will increase your SEO in any way. Robots know how to resolve relative URLs. What it will give you for sure is more data to send with each response (because of longer URLs). So please consider again is it worth to change.
About the issue itself you have to edit file /includes/vbenterprisetranslator_functions_url_tracking.php:
1. find:
PHP Code:
if (0 === strpos($address, 'vbet_flag-')) {
2. REPLACE by:
PHP Code:
if (false !== strpos($address, 'vbet_flag-')) {
This was not tested so please confirm does it solved your issue. If yes we will include it in next release (so you will have no troubles with upgrades)
