Why are certain features not available for Glide pages?

I’m really close to something I like. I have everything lining up nicely regardless of screen size and I can add and remove additional bars easily. The only issue I have is that low percentages look weird. I can correct it, but then I lose the number on the left side of the bar.

Here’s what I have right now. Notice that low percentages look good.

If I fix that issue, then I lose the number.

I’ll try some more, but I think the only solution is to remove the rounded corners, or make them less rounded.
