Some things to check.
The fluid level in the reservoir. There may be too much fluid in there, if the fluid was topped up between pad changes. It may not explain why only the right hand caliper drags though. Check it anyway, it is easy to do.
I don't know if you slackened the front axle bolt when doing the bouncing procedure. It is possible to get the right fork leg out of line if the right hand pinch bolts are used to hold the axle while tightening the axle bolt. The axle bolt should be free to draw the axle through the forks and clamp everything together. If you don't have the hex key large enough to fit the left hand end of the axle, then push the axle in as far as it will go and use the right hand fork pinch bolts to hold the axle still while tightening the axle bolt. Then release the pinch bolts to bounce the forks.
Make sure the pad spring is the correct way round - I don't know if your bike has 3 pistons on the caliper or just two, or whether it is possible to insert the pad spring for the 2 piston caliper the wrong way round. But if it has 3 pistons, it is definitely possible to get them the wrong way round. Then the wide strip of the pad spring goes closest to the pistons. Note the little tags that @BikerRic just mentioned as I was typing this !
Check that the pad retaining clips are correctly seated, and that the tongue at the forward end of the pad backing plate is seated properly in the retaining clip. The photo shows the pad and silver retaining clip for the rear wheel. But you get the idea.

Note that rear pads (as above) have a little notch in the tongue. Front pads do not. But note that the retaining clip for the rear has a little ridge in it which fits in that notch. If you have accidentally put the rear retaining clip in the front caliper, it will make it impossible for the pad to retract and will drag. (I seem to remember that the front and rear pads have the same size backing plate so checking which one is where may be a good idea - although the rear pads have much more friction material when new).
Check that the pad pin is not rusty, bent, ridged.
With the pads out, check that the caliper can move back and forth - grab it and push it in towards the wheel. It should move easily. Let go. Make sure it doesn't move by itself (too much grease on the slider pins). Pull it back and let go. Ditto. If it doesn't move easily, then you need to investigate the slider pins.
Do the pistons push in using just thumb pressure ? (Clean the pistons before pushing them in though). If not, check the tiny recuperation port in the master reservoir, under the silver disc at the bottom.
