Spanish 43 Mauser safety falls out
I recently acquired a Spanish Model 43 short rifle mfg. by La Coruna in 1945. It has an aftermarket safety. The safety functions normally, but when it is in the FIRE position (whether bolt is open or closed), the safety easily slides to the rear and all the way out. I made a little video of it, in case my description is not clear.

Do any of you more knowledgeable folks have any ideas as to what the problem is and how to resolve it?
Many thanks,
