wp_Query with mutuplea values returns all posts

Question

I have a dynamic form that brings the data from the URL and searches the DB with a wp_Query. It works great if I insert a dingle value manually. but if I pass the data from the URL I receive all the posts. even if I manually insert an array with multiple values it returns all posts.

here is the query: the first part works great. the second one cost_per_month_ipcenter_filter_new is the one with the problem.

    $args = array(
    'posts_per_page' => -1,
    'post_status' => 'publish',
    's' => $_GET['s'],
    'post_type' => 'ipcenters',
    'meta_query'     =>  array(
         'relation '  => 'AND',
        array(
            'meta_key'      => 'setupfee_ipcenter',
            'meta_value'        => $setupfee_ipcenter_val,
            'meta_compare'   => $setupfee_ipcenter_comp,
        ),
        array(
            'key'       => 'cost_per_month_ipcenter_filter_new',
            'value'     =>  array('101-150', '0-50'),
            'compare'   => '=',

        )
    ),
);


$the_query = new WP_Query( $args );

if I write

'value' => '101-150',

it works. I tried 'value' => ['101-150', '0-50'], This is the same as the written above but it still doesn't work.

this is how it appears in the url cost_per_month_ipcenter_filter_new%5B%5D=0-50&cost_per_month_ipcenter_filter_new%5B%5D=101-150

the final result it to place the $_GET['cost_per_month_ipcenter_filter_new'] as the value array.

What am I doing wrong?
