The software is assigning my fill to layers I don't want.

What i expected:  i create a layer for my line & shapes

                             i create a layer to fill the line & shapes

                             i select the fill layer, take the paint bucket and fill in the stroke

                             BOOM EVERYTHING WORK IVE GOT MY FILL ON A LAYER.. AND THE                                         STROKE ON ANOTHER!

What i got:            i create a layer for my line & shapes

                             i create a layer to fill the line & shapes

                             i select the fill layer, take the paint bucket and fill in the stroke

                             BUT FOR SOME REASON, THE COLOURS I FILLED GOT INTO MY LINE                                           LAYER AND NOT THE FILL LAYER(even though i selected the fill layer i created)

I dont know what is happening. im actually on the 7 days free trial version of the software... and everything was looking/feeling fine, until i hit that problem of paint bucket not filling on the layer i want it to and instead shift ans fill on another layer. AND ITS ANNOYING. i was hoping to learn the software and buy it as im an animator and really want to use Adobe Animate. As i said, im new here, maybe im doing something wrong, maybe theres a tweak somewhere to fix that problem... i even tried locking the other layers just to fill the layer i want... but then it doesnt.

pls if anybody got an explanation and help me.. i would appreciate it very much.

i have 6 days left of free trial.. and im stuck on the most important stuff.. THE LAYERS
