What map and what other mods? I have had no issues using the Exceptional stones with Wyverns. See the last dozen or so screens I just grabbed.

I play on Ragnarok. We have this one, death recovery mod, And Automated Ark. We've bred several more since then, mine is the only female lightening that is requiring the light blue- all of the rest are accepting yellows, except for the one fire that it none of them work for.
Oh, my husband says he just got yellow to work on his fire male- I'm a little confused as to why the different ones are doing this. >< Could it have something to do with their hatching stats?

Wyverns change their food settings during breeding maturation and likely its not replicating to clients in some cases. The default is the yellow stone. I think given time the wyverns will revert to normal. After grown and maybe a player relog and/or server restart.

All my wyverns were well grown and it had been at least several server restarts since adulthood before I even had finished this mod to try on them.

I also have a fire wyvern that is not accepting an Exceptional+ Stone. The game says "Can use" but does not allow me to actually use it.

Playing on Val.

I have the same problem. My fully grown Wyvern does not except any Stone. I tried the light blue one and the yellow one. On the yellow one it says can use but nothing happens. Is there a fix or a workaround yet? I play on Val on a private server

Wyverns should be yellow stones iirc. I have not tried them in a while but when I did months ago I was able to give them yellow without issue.
This was after they were full grown and server had definitely restarted since being full grown.
Wyverns change their food settings on server only while maturing. I suspect this confuses things for the revival stones. For efficiency in the interest of not adding to network load, the stones do not send server info to clients. Instead, they rely on the server and client coming to the same conclusion as to what stone is to be used.
I do not want to incur more net cost for all dinos using stones so I will look at adding something that does that for wyverns only. And I suppose in case xyz bbq9000 mod dinos have issue, i will have to put some ini setting to add more dino matches for this.

I've having the same issue with Ice Wyvern on SP.. sigh.
