So your block is inserted on layer P-STRP-PVMTXT which is green, but the blocks appear white.
What layer are the block components?? If they are on layer 0 and setbylayer, they will follow the layer settings of the layer on which they are inserted. If they are remaining white, then the components making up the block are either on a layer that's white,
OR the layer in the block already exists in the target drawing, and was set to white instead of the color of the original block drawing.
OR were set to something other than bylayer.
Open the file you used to create the blocks palette and check the blocks and/or layer settings there. Use REFEDIT or BEDIT to edit the block definition and check the properties of the components in the block.
