Split: Conflict with WooCommerce bookings

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing an issue where, in the original language (Spanish), the booking system allows booking more slots than available, despite the system working correctly in a translated language (Euskera).
Solution:
We recommend the following steps to address the issue:
1. Create a full site backup.
2. Navigate to

/wp-content/plugins/woocommerce-multilingual/compatibility/WcBookings/class-wcml-bookings.php

and edit the file.
3. Comment out the line by adding

//

at the beginning:

//add_filter( 'woocommerce_bookings_filter_time_slots', [ $this, 'fix_bookings_filter_time_slots_when_product_not_translated' ], 10, 3 );

4. Save the changes.
5. Ensure that the bookable product is duplicated or translated to all languages.
If this solution does not resolve the issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket.

rafaelF-23	Yes, sorry about that. Both the 5.50 version and the workaround work for the first mentioned problem which is counting people as reservations. But now we face a different issue, in one of the languages, although counting people as reservations correctly, i can still book more than the maximum slots availability. As you can see in the screenshot the available slots are 10, and I'm able to put 12 and continue the reservation. If you want i can try to reproduce this in the sandbox

rafaelF-23	Hi there, sorry for the delay. I can't seem to replicate the issue in the sandboox as i encounter another issue, the calendar in the translated version doesn't charge correctly. But in the original version, which is where we seem to have this issue, it works correctly. So what does this mean? Also, we are using the 5.51 version with the workaround, not sure if the sandbox has the same.

rafaelF-23	Hey, we did as you said, but unfortunately is still not working correctly. As said before, in the translated language (euskera) you can see it work correctly, but in the original (Spanish) it still let's me book more that the available spots. You can check with this product: hidden link

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi there, So, the issue happens only in the default language (Spanish). WPML plugins make no changes to the content or configuration in the default language. I kindly ask you to deactivate the WPML plugins and check if the problem in the Spanish bookable product persists.
