Onepress FEATURE pictures not aligned correctly

Hi,

Thanks you for your wonderfull theme, really awesome. I started using Onepress recently and it works great however i do experience two issues on which i can use a little support…

My issue: When resizing my site on my desktops Chrome (or IE) browser it doesn’t align the pictures correctly in the FEATURES part.

When width is 992px there is online 1 line and all 4 pictures are correctly aligned next to each other like:
XXXX

When width is 991px untill 768px it goes wrong. There are suddenly 3 lines. Two pictures are aligned on the first line (as one would expect), the third picture is aligned on line 3 and the fourth picture is aligned on line two like:
XX
X
X

When screen width is 767px untill 573px the pictures are correctly aligned like:
XX
XX

When screen width is 572px untill 544px it is going wrong again. the pictures getting aligned on three lines again like:
XX
X
X

From 543 downwards the pictures are aligned correctly below eachother in 4 lines like:
X
X
X

Hopefully you can provide support on this to get this issue solved.

Thanks in advance!
