I replaced all of the bulbs in the track light with LEDs. I also replaced the two switches with LED compatible smart switches (dimmers). The furthest light on the track has been flickering and recently the next one has started to flickers as well. The flickering started when I changed the bulbs to LED and I figured that changing the switches would fix it, it didn't. Do I have to replace the track lighting completely with "LED Compatible" ones?

There are LED replacement kits that include a bulb, power supply, and trim ring (if you are not wed to your existing ones). They may be less deep than the bulbs you are finding. The bulb base is separate from the rest of the unit to reduce space and ease installation.

You probably have 4 rails there, just two happen to be in-line, on either side of the power input (gray block in center.)
Your problem is likely at the right side (in the picture) corner connector. Given that the power supply appears to be shared, the power supply would seem to be fine given the working lights - but the conductors are not conducting around the corner. Exactly why is hard to determine remotely, but that's where to look.

If you look on the box/packaging that the LED bulbs came in, they will tell you the type of switch they require. Some LED bulbs work fine with CFL dimmers (which are the cheaper one's that some manufacturer's will say can dim LEDs) but the majority of 120v LED bulbs require an ELV dimmer.
Another thing worth noting is that a lot of smart dimming switches are rated for about 150W. Common LED bulb wattage is at around 9W. This means that switch will only support up to 16 bulbs.
And lastly, if you have any mixed bulb type/vendors on the circuit, it can also cause flickering/conflicts.
