Some character animations shows only in animation editor browser but won't show in sequencer to add them ?

I have a weird issue with animation assets for a character I am working on. I wanted to add some animations to the character in sequencer but they do not show in the search bar when in sequencer timeline. The animation shows only in the animation editor like in the attached screenshot. When I force the animation and add it to the character in the timeline by dragging it from the asset browser in animation editor to the timeline, the character goes to the default mannequin base pose but in the animation editor it plays with no issues ! am I missing option to check or what ?
