Small modifications in Wordpress theme + fix multilanguage issues

I need the below changes/fixes done on a wordpress website built using a theme called MIES. The websites uses Polylang and Loco Translate plugins and it's built in English and Greek. Some of the issues have to do with incompatibility of the theme with the multilanguage functionality (no translation needed here, just fixes to show the correct language in the correct places, content is already there). 1. In projects page ([login to view URL]), when the page first loads, the filtering doesn't work, when I click on filtering links nothing happens. If I refresh the page, filtering works great 2. On projects page, I want to only show the projects of the selected language. It now shows all projects from all languages. When I'm viewing the English projects page ([login to view URL]), I want to be able to see all and filter only amongst all projects of English language, when I'm viewing the Greek project's page ([login to view URL]), I want to be able to see all and filter only amongst all projects of Greek language. 3. In all grids showing projects (in frontpage or in projects page, in all languages), give enough space between project rows to fit 2 lines of project title. For example, P217 title takes 2 lines, P183 title takes 1 line, this creates misalignments in grids. If all projects in grid have enough space for 2 lines of title, all boxes in the grid will be aligned 4. In projects page ([login to view URL]) (in both languages), I need to have a specific order in which the filters appear. Please find how this is adjusted and show me how. If you go Filter by Year, it should go 2002, 2003, 2004, 2005 etc, not 2005, 2004, 2003, 2002 5. In the homepage slider that shows projects, I need the title of the project to always be in one line. Find a way to make that font size smaller in order to fit about 40 characters of title without breaking the line and without getting out of the width that the title currently takes. The same should apply when I click and open the project's page 6. Change the background colour of the footer of the page to white (currently it is dark grey). Change the font color of all the text that appears on the footer to black (currently it is white).
