Xbox One Delvin gave me 2 jobs but I can only do 1.... please help!

Title says it all. I talked to Delvin about fishing job, he didn’t give it to me. Probably just exited out to soon, right? Wrong. I talk to him and get a numbers job but then suddenly I also get a fishing job. Weird but ok. I go and do both jobs but when I return I can only quit/complete one job then he offers me more work and I can’t complete the other. To add to this, I can’t take the job I didn’t complete. Example: if I complete the fishing job and talk to him for more work I can’t get another numbers job. Lastly, I screwed up and saved over the previous save so now I can’t go back to before he gave me the jobs. I tried a bunch of stuff to fail/complete both jobs but nothing has worked so far. I’m also worried that I won’t be able to do special jobs since I’ll already have a job from Delvin. I’ve never run into this issue before so and advice on this would be greatly appreciated. Thanks!
