total_salary Parameter not observed

[bvoorhees13]

I'm sure this is user error but I'm trying to use the generic functions to build a DK CFB optimizer but it outputs the optimal lineup considering positional constraints but goes over the salary_total. In the example below the optimal lineup is $53,600.
It appears as though my data tibble is in the correct format with the correct data types and column names for the 10 columns. Using R version 4.2.2 here is the code with the output below it. Strangely, when I reduce the total_salary to 27,000ish or below it starts to constrain based on salary. Any suggestions to help me de-bug would be appreciated.

`model<- model_generic(DK_Projections, total_salary=50E3, roster_size=8, max_from_team = 5,
type = "binary")
constraints <- list(
"QB" = 2,
"RB" = 2,
"WR" = 3,
"RB/WR" = 1
)

model <- add_generic_positions_constraint(model, DK_Projections, constraints)

optimal<-optimize_generic(DK_Projections, model, L = 1, solver="glpk", bans=NULL,
locks=NULL, stack_sizes = NULL, stack_teams = NULL,
min_salary = 49000, randomness = NULL)
optimal
sum(optimal[[1]]$salary)
`

Here is the output:
