1. Is "Golf clubs" a connect iq app, or is it something else?
2. If It is an app, did you initially try to install it from the "Connect IQ" mobile app, or Express?
If Golf clubs is not a Connect IQ app and was not installed from the Connect IQ Mobile app, you would need to make a post in the Express forum which can be found here https://forums.garmin.com/apps-software/
Kaity_y Devices do have a CIQ app limit. Some devices it is 16 and some it is 32. Even if there is empty space on the device it will not allow more than this number. Can you confirm that you are not hitting this limit?
I'm having this same issue. There is a watchface in my queue that won't download and I can't remove it from the queue. I am getting error messages that there is not enough storage for it to install but there is plenty of room. I just need to be able to remove it from the queue to stop this bugging!
