Magento 2 Pagination Tab Issue Fix

Hello We have a site being developed in Magento 2.2 on the product page we have made some changes to the original theme - by adding a second tab section and also Pagination. Current issues are that the Tabs are not focusing on correct location when being used in mobile. Pagination developed - is not stable - it is moving randomly and not useable. We have a video we can provide link for to see the issue and also accompanying text file to explain the issue. We require only a specialist magento expert for this so if you have 0 feedback then please dont apply - we need this work done urgently so please dont apply if you can not start immediately and are fully dedicated to this task. MUST BE COMPLETED IN 2 DAYS No exception or delays dont bid if you can not do this. We have other magento 2.2 related work still left of site which we can discuss once the issue has been resolved successfully. We will require documentation of any changes to files and any files changes need to be backed up, clean code showing any changes made by the freelancer - very important task will not be complete until this is provided!
