Latex paint peeling
I recently bought my first home and I have decided to change up some colors. The fire place mantle was an off white color. I went to lowes and purchased valspar latex paint. I am a newbie to this, but I just painted over what was already there. After it dried it peeled right off with ease. Someone told me to strip what i painted off and sand down the original paint. Today I did that and repainted a portion of the top. I let it dry and sat something down on it when I picked it up the little rubber feet left marks on the paint. I took a screw driver and scraped it to see if it would peel again, but it didnt like before. I'm pretty much lost on what I need to do here.

Latex paint needs 30 days to cure to its full hardness.

When in doubt, PRIME WITH A BONDING primer to ensure adhesion to the old painted surface. Scuff sand, remove dust, and prime with 1-2-3 found at any paintstore or big box store. Then, listen to ChrisN, let the paint cure properly before setting stuff onto the surface.

Also - some paints are made for trim and dry harder with less stickiness ( painters call that blocking).
Cheaper semis are the worst.
If you really want to use a quality product- get a waterborne enamel at a real paint store.
There is a difference in the quality of the ingredients.

Regardless of where you buy the product, prep is necessary to achieve proper bonding; the primer idea is a good one. Most architectural paint products (wall/trim) will "block" early in the curing process. Two ways to avoid this: apply a waterborne industrial product, or apply a porch and floor product, which dry to a harder film.
