Fixing WPML plugin (Wordpress)

I have a couple of small issues cause by my Wordpress Multilingual (WPML) plugin and Woocommerce Checkout Manager Plugin not working correctly. I need someone to make the plugin work correctly. (I will provide access to the latest version of the plugins). The problems that I have now are: 1) (see screenshot) On my Checkout page (made with woocommerce checkout manager). I have some strings that I cannot find in the WPML plugin and therefore can't translate. Also there are strings that I can find in the plugin and that I have translated but the translation does not show on the page. Finally I want to remove the label "Select an option" (there is a css box in the checkout manager plugin). 2) (see screenshot) In the checkout manager plugin I am using two different calendars for delivery dates based on the type of product that is checked out (some products need longer before they can be shipped). One calendar is working fine but when the second calendar is shown there is no space between that field and the next field. This need to be fixed. 3) (see screenshot) On the order confirmed page there are fields that are not translated and it shows twice a delivery date field. (eventhough 1 is filled in) 4) (see screenshot) My site is in English and Dutch. However if a english translated mode is on, the card widget does not translate automatically but sticks to dutch (the cart page itself will translate) It is very important that these fixed will not get lost when updating the plugins. I prefer that the WPML plugin will be fixed instead of quick fixed for these individual issues. Also, I can provide temporary admin and ftp access. Finally I will have many jobs in the future as well. If cooperation goes well we can discuss working together regularly in the future as well.
